Since 2013, excavations have been conducted by French National Institute of Preventive Archaeological Research (INRAP in French) in Vienne where evidence was found of "one or more camps of Prehistoric hunter-gatherers, who also fished due to fishing traps found there. They were Neolithic farmer-herders, who were present in the area around 6,000 BCE (8,000 years ago).{{cite book |title=Blois de la préhistoire à nos jours |date=2019 |publisher=Éditions Petit à Petit |pages=82|language=fr}}

A major urban development begun in 1959 uncovered the remains of a late Gallic settlement and an urban centre from the Gallo-Roman period. At that time, the town was located on the road linking Chartres to Bourges.{{cite book |last1=Denis |first1=Yves |title=Histoire de Blois et de sa région |date=1988 |isbn=2-7089-8258-3 |pages=318 |publisher=Privat |edition=Toulouse, Privat}} In the network of cities of the Carnutes people, Blois was a secondary settlement. Excavations carried out on the right bank between 2001 and 2016 and on the left bank in 2013-2014 revealed the presence of a large developed town on the right bank and an occupation on the left bank from the Gallic and Gallo-Roman periods. The Loire river has undoubtedly always been a major axis route, although no traces of a port have been discovered. However, there are remains of former bridges linking the two banks.{{cite book |last1=Denis |first1=Yves |title=Histoire de Blois et de sa région |date=1988 |isbn=2-7089-8258-3 |pages=318 |publisher=Privat |edition=Toulouse, Privat}}

Though of ancient origin, Blois is first distinctly mentioned by Gregory of Tours in the 6th century, and the city gained some notability in the 9th century, when it became the seat of a powerful countship known as Blesum castrum by the counts of Blois.{{Cite web|url=http://www.artwarefineart.com/gallery/chateau-de-blois-st-nicholas-cathedral-blois-river-loire|title=The Chateau de Blois & St Nicholas Cathedral, Blois from the river Loire Artware Fine Art|website=artwarefineart.com|access-date=5 August 2017}}

The Robertians were at the head of the county of Blois before 900. When Hugh the Great became duke of the Franks, he left the title of count to his faithful vassal, Theobald I of Blois (circa 940).{{cite web |last1=Raphaël Bijard |title=Les Thibaldiens: origines, premières alliances et ascension politique |url=https://www.academia.edu/95920541 |website=Academia |date=2022}} His descendants, known as "Thibaldians", remained as Counts up until the county became a royal possession in 1397. The House of Blois also succeeded in raising some of its members or descendants to the highest levels of the European nobility, notably by acceding to the thrones of France, England, Navarre, Spain and Portugal.{{cite book |author=Collective |title=Blois de la préhistoire à nos jours |date=2019 |pages=82 }}

In 1171, Blois was the site of a blood libel against its Jewish community that led to 31 Jews (by some accounts 40) being burned to death.[http://www.chabad.org/library/article.asp?AID=112387 The Martyrs of Blois] Their martyrdom also contributed to a prominent and durable school of poetry inspired by Christian persecution.Jewish Poetry And Martyrdom in Medieval France. Susan L. Einbinder. Princeton University Press. 2002. In 1196, Count Louis I of Blois granted privileges to the townsmen; a commune, which survived throughout the Middle Ages, probably dates from this time. The counts of the Châtillon dynastic line resided at Blois more often than their predecessors, and the oldest parts of the Château of Blois (from the 13th century) were built by them.

In the Middle Ages, Blois was the seat of the County of Champagne when the latter passed to the French crown in 1314, forming the province of Champagne within the Kingdom of France.{{Cite EB1911|wstitle=Champagne|volume=5|last=Longnon|first=Auguste|author-link=Auguste Longnon|pages=827–828; see page 828, first para, last sentence|quote=Louis Hutin, became count of Champagne. He was the last independent count of the province, which became attached to the French crown on his accession to the throne of France in 1314}} By 1397, Count Guy II of Blois-Châtillon offered the county to his cousin, Duke Louis I of Orléans, brother of King Charles VI. In 1429, Joan of Arc made Blois her base of operations for the relief of Orléans. She rode the 35 miles on 29 April from Blois to relieve Orléans.Smith, John, Holland (1973). "Joan of Arc." New York: Charles Scribner's Sons In 1440, after his captivity in England, Duke Charles of Orléans (son of Duke Louis I) took up residence in the Château of Blois, where in 1462 his son was born, Duke Louis II of Orléans who would afterwards become Louis XII.

By 1498, King Charles VIII died with no heirs in the Château of Amboise. Subsequently, Duke Louis II ran {{cvt|22|mi|order=flip}} between the Château and Blois, and was crowned King Louis XII of France. He then married Charles VIII's widow, Queen Anne of Brittany, in 1499. The birth of their daughter, Claude of France, effected the union of Brittany with the France. Louis XII, as the last hereditary Count of Blois, naturally established his royal Court in the city. The Treaty of Blois, which temporarily halted the Italian Wars, was signed there in 1504–1505. During his reign, the city experienced a massive redevelopment, with some architectural elements inspired from the Italian Renaissance, as seen in the medieval castle immediately turned into a château, and the construction of many hôtels particuliers for the nobility throughout the entire kingdom. One of which, Hôtel d'Alluye, was built as a copy of an Italian palace for Florimond Robertet, who was an important French minister under King Charles VIII, King Louis XII and King Francis I.

On 1 January 1515, Louis XII died. His throne would be passed to Francis I, the husband to his daughter, Claude of France. In 1519, King Francis I ordered the construction of the Château of Chambord (10 miles away from Blois), but its construction lasted for one year before he died in 1547. In the meantime, he gradually expressed his will to move to Fontainebleau, near Paris, and started to abandon Blois. Much of the royal furniture was moved from Blois to Fontainebleau by 1539.

The French Wars of Religion were a significantly destructive conflict for the French people. The city's inhabitants included many Calvinists, and in 1562 and 1567 it was the scene of struggles with the Catholics. On 4 July 1562, Blois and Beaugency, conquered by Protestants just before, were looted by the Catholics led by Maréchal de St. André. On 7 February 1568, Protestants under Captain Boucard's command, looted and invaded the town, eventually killing many Catholics. Grey friars were also killed and thrown in the well of their own convent. In addition, all the churches were ransacked. In 1576 and 1588, King Henry III convoked the Estates General to Blois where he attained refuge after an uprising called the Day of the Barricades. In response, Duke Henry I of Guise was assassinated on 23 December 1588 for his involvement in the uprising. The following day, his brother, Cardinal Louis II of Guise, who was also Archbishop of Reims, suffered the same fate. Their deaths were shortly followed by that of the Queen-Mother, Catherine de' Medici.

In the 16th century, the French Royal court often made Blois their leisure resort.

After the departure of the Royal Court towards Paris, Blois lost the status of a Royal residence, along with the luxury and economic activity that came with it. King Henry IV relocated the Royal library to Fontainebleau, which would later be the National Library of France ({{Lang|fr|Bibliothèque nationale de France}}).

In 1606, Philippe de Béthune gave his ownership of Vienne-lez-Blois village, on the left bank of the Loire river, to Blois, making it a part of the city afterwards known as Blois-Vienne. From 1617 to 1619 Marie de' Medici, wife of King Henri IV, exiled from the court by his son, King Louis XIII, lived in the château. By 1622, the Counter-Reformation arrived in Blois and a Society of Jesus was founded. St. Louis Chapel, which is today St. Vincent Church was also built at this time.

Then in 1634, Louis XIII exiled his brother, Gaston, Duke of Orléans and Count of Blois, who became attached to the city. The Duke in 1657, found a hospital in Blois-Vienne, now named Résidence Gaston d'Orléans, and financed the reconstruction of the Hôtel-Dieu. He remained in Blois until his death, in 1660.

Under Louis XIV's reign, Blois became un independent bishopric. David Nicolas de Bertier, first bishop of Blois from 1697, chose as his seat the cathedral church of St. Solenne, that had been destroyed by a storm and was under reconstruction, before being completed 3 years later in 1700, thanks to the intervention of Colbert's wife, who herself came from Blois. The new edifice became Blois Cathedral and was dedicated to St. Louis.

A large episcopal palace was built by King Louis XIV's official architect, Jacques Gabriel, right next to the newly built cathedral, on a site overlooking the Loire Valley. Landscaping of terraced gardens began in 1703 and lasted nearly 50 years. The so-called Bishopric Gardens were first open to the public in 1791 by Henri Grégoire (known as the Abbot Grégoire), the first constitutional bishop after the French Revolution.

During the night of 6-7 February 1716, the medieval bridge collapsed. Construction of a new one was ordered the following year. Jacques-Gabriel Bridge was inaugurated in 1724. All the levies were consolidated, and the river channel of La Bouillie in the prolongation of La Creusille Harbour was closed and dried.

When Duke Gaston of Orléans died, the château was stripped by King Louis XIV, and completely abandoned, to the point that King Louis XVI once considered demolishing it in 1788. The building was saved when the Royal-Comtois Regiment established their base within it.

In 1790, Orléanais province was dissolved, the Département of Loir-et-Cher was created with Blois as the local capital.

By 1814, Marie Louise, Duchess of Parma and wife of Napoleon I, found refuge in Blois.

There was new development in Blois in the 19th century. Firstly, the railway arrived in 1846 with the inauguration of the Paris–Tours railway, whose Blois Station is a stop. The competition with river transport gradually forced La Creusille Harbor to reinvent its activity. In parallel, the city became more industrialised from 1848 thanks to a successful chocolate brand created by Bloisian, Victor-Auguste Poulain.

As in Paris, urban organisation in Blois was redesigned during 1850 and 1870 by Mayor Eugène Riffault, who was friends with Baron Georges-Eugène Haussmann. Thus, he had built a boulevard separating the modern upper town (where the cathedral, Hôtel of Préfecture, and Halle aux Grains are located), from the medieval lower town. He also paved the way to the construction of the boulevard Daniel Depuis, in the West of Blois. Between 1862 and 1865, the Denis-Papin staircase are built under La Morandière's supervision, in the axis of Jacques-Gabriel Bridge and Blois-Vienne's Wilson Avenue.

In the meantime, the lower town faced three of the most significant floods of the Loire river: in 1846, 1856 (the worst), and 1866. The central districts of St. Jean and Blois-Vienne were under water, as well as La Bouillie spillway.

On 13 December 1871, the Prussian army took control of Blois during the Franco-Prussian War. The city was taken back by Lieutenant Georges de Villebois-Mareuil, General Joseph Pourcet, and General Bertrand de Chabron. Since then, a memorial stands on Wilson Avenue in Vienne.

In 1939, the construction of Blois Basilica was completed. That same year, between 29 January and 8 February, more than 3,100 Spanish refugees came to the Loir-et-Cher department, fleeing the Spanish Civil War and Dictator Francisco Franco. In June 1940, the German bombings destroyed a large part of the centre, and the French destroyed the 10th arch of Jacques-Gabriel Bridge to prevent further advance for the enemy. The German army bombed the former Town Hall on 16 June, thus killing Mayor Émile Laurens in the process, and took over the city 2 days later, on 18 June, the exact same day of Charles de Gaulle's Appeal for Internal Resistance.

Between June and August 1944, US-English-allied bombings destroyed other infrastructures, like the railway bridge between Blois and Romorantin. In total during World War II, 230 people were killed, and 1,522 buildings were entirely or partially destroyed. On 16 August 1944, the German troops withdrew to Blois-Vienne to seek refuge and destroyed the three central arches of the bridge. On 1 September, they surrendered. The bridge was rebuilt and reopened in December 1948.

In 1959, Mayor Marcel Bühler received President Charles de Gaulle and launched the construction of the ZUP, at the North of the city, on the same model of so-called banlieues of Paris or any other French city.

The Château of Blois, a Renaissance multi-style château once occupied by King Louis XII, is located in the centre of the city, and an 18th-century stone bridge spans the Loire. It was also the residence of many Counts of Blois, who were amongst the most closest vassals to the King of France between the 9th and the 14th century. Many gardens are located around the château, like:

• the St. Sauveur Garden (Parterre Saint-Sauveur in French);
• the Lily Garden (Jardin des Lices);
• the King's Stronghold (Bastion du Roi), and;
• Victor Hugo Square (Square Victor Hugo).

Right in front of the château, La Maison de la Magie Robert-Houdin (i.e.: Robert-Houdin House of Magic) is a museum dedicated to illusionism. This is the only public museum in Europe which incorporates in one place collections of magic and a site for permanent performing arts, and directly reflects the personality of Robert-Houdin.[http://www.virtourist.com/europe/chambord/22.htm Blois, La Maison de la Magie] at virtourist.com{{cite web|url=http://www.whatsonwhen.com/sisp/index.htm?fx=event&event_id=165816 |title=Mussee de la Magie. |url-status=dead |archive-url=https://web.archive.org/web/20110718040351/http://www.whatsonwhen.com/sisp/index.htm?fx=event&event_id=165816 |archive-date=18 July 2011}}{{cite web|url=http://www.travelsignposts.com/Paris/paris_museum-magic.php|title=Travel signposts, Paris Museum of Magic.|url-status=dead|archive-url=https://web.archive.org/web/20110302091632/http://www.travelsignposts.com/Paris/paris_museum-magic.php|archive-date=2 March 2011}}{{cite news|url=https://www.washingtonpost.com/wp-dyn/content/article/2005/06/10/AR2005061001074.html|title=Keck, Gayle, Washington Post, And Now for Paris' Next Trick. | newspaper=The Washington Post| date=12 June 2005 | access-date=23 April 2010}}

Opened after bombings in 1944, the place stands right below the château, closest to the Loire river, and is actually located at the centre of Blois downtown. There are local shops and restaurants, and a 16th-century fountain stands below the Sycamores planted in the place. Known as Louis XII Fountain (Fontaine Louis XII), this is one of the greatest and oldest water inlets throughout the city, but far from being the only one. Among the other founts, there are:{{cite web |last1=Emmanuelle Plumet |title=Laissez-vous conter le parcours des fontaines de Blois |url=https://www.culture.gouv.fr/Media/Medias-creation-rapide/Laissez-vous-conter-le-parcours-des-fontaines-de-Blois.pdf |archive-url=https://web.archive.org/web/20220321140550/https://www.culture.gouv.fr/Media/Medias-creation-rapide/Laissez-vous-conter-le-parcours-des-fontaines-de-Blois.pdf |archive-date=2022-03-21 |url-status=live |website=Ville de Blois |publisher=French Minister of Culture}}

• St. Martin Fountain (Fontaine Saint-Martin), below the staircase between the château and Louis XII Place;
• St. Nicholas Fountain (Fontaine Saint-Nicolas), within the St. Nicholas Church;
• Elected Representatives' Fountain (Fontaine des Élus), in rue Foulerie;
• Ave Maria Fountain (Fontaine Ave Maria), in place Ave Maria;
• Town hall Fountain (Fontaine de l'Hôtel de Ville), below the Denis Papin staircase (where was the former Town Hall before World War II);
• St. Jack Fountain (Fontaine Saint-Jacques), in rue Denis Papin;
• Corbigny Fountain (Fontaine de Corbigny), in Victor Hugo Square ;
• Simple Fountain (Fontaine des Simples), in the Lily Garden, in remembrance of a monumental Versailles-style fountain lost after WWII bombings.

Blois is also the location of so-called Maison de la BD, a museum devoted to the art of comic books.{{cite web | url=https://www.blois.fr/en/attractive/remarkable/comic-strip-house | title=Comic strip house }} Since the 1980s, this museum hosts an annual comic festival in late November called BD Boum,{{cite web | url=https://maisondelabd.com/information | title=Bd BOUM annulé }} described as "the leading free comic book festival in France".{{cite web | url=https://www.blois.fr/en/attractive/festive/bd-boum | title=Bd BOUM (Comics festival) | date=22 November 2019 }}

Already by 924, monks from the St. Lomer community were given some acres below the medieval castle, but outside the city walls, on the bank of the Loire river. In the 13th century, a proper church was built, then fortified because of the Hundred Years' War. St. Lomer Abbey was completely destroyed during the French Wars of Religion. The edifice was rebuilt until the early 18th century. When the French Revolution broke out by 1789, the church was turnt into a Hôtel-Dieu, namely a charity hospital for the have-nots, because Revolutionners destroyed many clergy- and royal-related monuments. After that, new buildings were added to the original St. Lomer Abbey, which became St. Nicholas Church, and the additional edifices remained dedicated to the Hôtel-Dieu of the city. Nonetheless, this part was gradually abandoned and taken back by some public services. A reconversion project is currently under study.

In the late 19th century, Bloisian industrialist and chocolatier Victor-Auguste Poulain established his brand's factory next to Blois station. The premises moved in the 1980s. Nowadays, those are housings and host the National Institute and School of Applied Sciences (INSA).

As Blois is built on a pair of steep hills, winding and steep pathways run through the city, culminating in long staircases at various points. The most iconic of them is the monumental Denis-Papin staircase which overlooks the town, provides a panoramic view by overlooking the downtown and the Loire Valley, and regularly enlivens urban space with original decorations.{{cite web |last1=Blois Town Hall official website |title=Denis-Papin staircase |url=https://www.blois.fr/en/attractive/remarkable/denis-papin-staircase#/gallery-id-7888 |website=blois.fr}} The fountain next to the staircase is a reminder of the location of the first Town Hall, destroyed after bombings on 16 June 1940.

Blois achieved independence from the Diocese of Chartres in 1697, and the cathedral was completed by 1700. As a result, the first bishops engineered wide gardens on several levels, next to the premises. Since the destruction of the former Blois town hall during World War II, local authorities requisitioned the bishop's apartments to establish there the new town hall. Now organised as an urban park, the gardens offer a panoramic view on the downtown, the Loire river, and Blois-Vienne. A statue of Joan of Arc, given to the city by American patron J. Sanford Saltus, stands in the middle of the park. Bishopric gardens are open to public all the year, and a remarkable rose garden can be visited from 15 May and 30 September, each year.

Since Count Louis II of Orléans became King Louis XII of France in 1498, the city started to host many noblepersons from all the Kingdom. All would build their own mansion as close from the château as they could. King Louis XII also imported Renaissance style from Italy due to his successful military campaigns there. Among these so-called hôtels particuliers, there are:

• the Hôtel d'Alluye;
• the Hôtel d'Amboise;
• the Hôtel de Belot;
• the Hôtel de la Capitainerie (a.k.a. Hôtel de Bretagne);
• the Hôtel de la Chancellerie (i.e.: Chancellery Hotel);
• the Hôtel Denis-Dupont;
• the Hôtel d'Épernon;
• the Hôtel de Guise;
• the Hôtel de Jassaud;
• the Hôtel de Lavallière, built for Louise de Lavallière;
• the Hôtel de Rochefort;
• the Hôtel Sardini;
• the Hôtel Viart;
• the Hôtel de Villebresme, in which Denis Papin lived;
• the Château de la Vicomté (i.e.: Château of Viscounty), in the hamlet of Les Grouëts.

In addition, many citizens from the peoples engineered timber-framing buildings all across the city, including:

• the Logis du Loup;
• the Maison des Acrobates.

Please note all the above edifices have been listed as historical monuments.

Blois-Vienne (or merely Vienne) is the name given to the southern part of the city, on the left bank of the Loire river. Independent from the city until 1606, there are many traces of the river's past. The main link between both banks is the Jacques-Gabriel Bridge, built in the early 18th century. From the levees circling the surroundings to other abandoned bridges, Vienne has also conserved a harbour, named La Creusille, which is now an urban park right on La Loire à Vélo bike route.{{cite web|title=La Creusille Harbour|url=https://www.blois.fr/en/annuaire/parcs-jardins-espaces-naturels/port-creusille|author=the Blois City Official Website|website=blois.fr|date=2022}} Beyond the levees, La Bouillie Park is getting rehabilitated, and actually is a spillway in the event of floodings. Further to the south of the city, the Forêt de Russy is a reminder of the thick woods that once covered the area.

The city also is provided with many religious edifices, including:

• Blois Cathedral, dedicated to both Kings Louis IX and Louis XII, built between 1564 and 1700.
• St. Vincent Blois Church, dedicated to Saint Vincent de Paul, built between 1625 and 1660.
• St. Nicholas Blois Church, dedicated to bishop Saint Nicholas of Myra, built in the 12th century.
• Blois-Vienne Church, dedicated to Saint Saturnin of Toulouse, built between c. 1500 and 1528.
• The Basilica of Notre-Dame de la Trinité, dedicated to Our Lady of the Holy Trinity, built between 1932 and 1939.
