Cornish promontory forts, commonly known in Cornwall as cliff castles, are coastal equivalents of the hill forts and Cornish "rounds" found on Cornish hilltops and slopes. Similar coastal forts are found on the north–west European seaboard, in Normandy, Brittany and around the coastlines of the British Isles, especially in Wales, Scotland and Ireland. Many are known in southwest England, particularly in Cornwall and its neighbouring county, Devon. Two have been identified immediately west of Cornwall, in the Isles of Scilly.{{cite web|last=Anon|title=Farms, villages and towns|url=http://www.historic-cornwall.org.uk/flyingpast/images/PDF_downloads/Farms,%20villages%20and%20towns.pdf|pages=15 17|publisher=Historic Environment Service|accessdate=29 September 2012}}
A promontory fort is a coastal headland, isolated from the mainland by one stone, turf or earthen rampart (a univallate fort), or more than one (a multivallate fort). Some promontory forts also have ditches, created by the excavation of material to form the rampart. British promontory forts were constructed during the Iron Age, and remained in more-or-less continuous use into the early Roman period. Their function remains uncertain. They would have offered ready access to sea-routes but those built in particularly inhospitable settings may have had only occasional or seasonal use. Inland hillforts show signs of human habitation and other uses before and after the Roman era, but cliff castles were occupied sparsely, if at all. Some hill forts abandoned during or before the Roman era were reoccupied from the post-Roman to early medieval eras but in the same period cliff castles fell into disuse. Some were quarried for their building stone.{{cite web|title=Lankidden|url=http://www.historic-cornwall.org.uk/a2m/iron_age/cliff_castle/lankidden/lankidden.htm|publisher=Cornwall's Archaeological Heritage|accessdate=28 October 2012}}
Treryn Dinas is one of the few Cornish promontory forts to have been systematically excavated. Archaeologists believe it might have been developed from a Bronze Age site of ceremonial, religious or social significance to the surrounding community.{{cite book|last=Dudley|first=Peter|title=, Hal, Cliff and Croft: The Archaeology and Landscape History of West Cornwall's Rough Ground|year=2011|publisher=Historic Environment Service|location=Truro|isbn=1903798728|pages=185}} Possible ancient contexts and uses of Cornish cliff castles have been a subject for study and speculation by antiquarians such as William Borlase. Modern sources agree that cliff castles may have served principally as prestigious sites for religious ceremonies, trade and administration, and that their defensive capacity may have been a secondary function.
The following cliff castles in Cornwall are listed by geographical location from the border with Devon at the Marsland Valley, west to Land's End and east via The Lizard to Cremyll overlooking Plymouth Sound. Unproven or uncertain sites are in italics.

''Dizzard''
The Dizzard ({{gbmapping|SX 167989}}) is an area of slumping cliff in the parish of St Gennys. The site is within the Boscastle to Widemouth SSSI and is known for its lichen communities which are of international importance. The promontory fort identified by the West Cornwall Field Club is probably a natural feature.{{cite web|title=Monument No. 434654|url=http://www.pastscape.org/hob.aspx?hob_id=434654&sort=4&search=exact&criteria=st%20gennys&rational=q&recordsperpage=10&p=1&move=n&nor=110&recfc=0|work=Pastscape|publisher=English Heritage|accessdate=28 October 2012}}
''Castle Point''
Castle Point ({{gbmapping|SX144978}}) is claimed as a possible site by the West Cornwall Field Club. English Heritage describes it as a probably natural feature.{{cite web|title=Monument No 434663|url=http://www.pastscape.org/hob.aspx?hob_id=434663&sort=4&search=exact&criteria=st%20gennys&rational=q&recordsperpage=10&p=1&move=n&nor=110&recfc=0|work=Pastscapes|publisher=English Heritage|accessdate=28 October 2012}}
Willapark (Boscastle)
{{main|Willapark (Boscastle)}}
Willapark (Boscastle) ({{gbmapping|SX090913}}) is a headland to the west of Boscastle with a former coastguard lookout on the summit. It has a single 110 m straight bank, indistinct to the south-west and up to 1.8 m high, with a ditch on the landward side at its north-eastern end. The present path onto the headland may indicate the original entrance. The fort overlooks Forrabury Common, a medieval field system.{{cite web|title=Monument No. 432081|url=http://www.pastscape.org/hob.aspx?hob_id=432081&sort=4&search=all&criteria=forrabury&rational=q&recordsperpage=10|work=Pastscapes|publisher=English Heritage|accessdate=5 November 2012|url-status=dead|archiveurl=https://web.archive.org/web/20160819083434/http://www.pastscape.org/hob.aspx?hob_id=432081&sort=4&search=all&criteria=forrabury&rational=q&recordsperpage=10|archivedate=19 August 2016}}
''Dinas Head''
Dinas Head ({{gbmapping|SW848762}}) is on the western side of Trevose Head within the parish of St Merryn. The headland is a Scheduled Ancient Monument and is included in a list of cliff castles awaiting classification. Aerial photographs show no sign of earthworks on the neck of the headland.{{cite web|title=Dinas Head|url=http://www.pastscape.org.uk/hob.aspx?hob_id=429464&sort=2&type=&rational=a&class1=None&period=None&county=None&district=None&parish=None&place=St%20Merryn&recordsperpage=10&source=text&rtype=&rnumber=&p=3&move=n&nor=73&recfc=0|work=National Monuments Record|publisher=English Heritage|accessdate=25 September 2012}}
Winecove Point
Winecove Point ({{gbmapping|SW854738}}) is to the south of Treyarnon Bay, within the parish of St Merryn. It comprises three headlands, situated between White Cove and Wine Cove, each of which is registered as a separate Ancient Monument. The South West Coast Path passes on the east side of the entrance(s).
''Trevelgue Head''
Trevelgue Head ({{gbmapping|SW825630}}) is a scheduled monument a short distance north-east of Newquay. The defensive ramparts of the fort, and two round barrows dating from the early Bronze Age, can be seen. With seven ramparts, Trevelgue is among the most defended prehistoric sites in Cornwall.{{cite book |author1=Philip Payton |author1-link=Philip Payton |title=Cornwall: A History |date=2017 |publisher=University of Exeter Press |location=Exeter |isbn=9780859890274 |page=46 |edition=3rd}} An archaeological excavation of the site in 1939 by C. K. Croft Andrew was discontinued on the outbreak of war, and the findings were not published until many years later. There are foundations of Iron Age roundhouses, of the 2nd century BC. There is evidence of bronze and iron smelting, and many items of worked stone, shards of decorated pottery, and objects of tin, copper and iron were found.[https://historicengland.org.uk/listing/the-list/list-entry/1006712 Promontory fort and two bowl barrows at Trevelgue Head] Historic England, accessed 29 June 2016.[http://www.cornwalltour.co.uk/trevelgue_head.html Trevelgue Head Cliff Castle] Cornwall Tour, accessed 29 June 2016.[http://www.cornwalls.co.uk/history/sites/trevelgue_head.htm Trevelgue Head] Cornwall Guide, accessed 29 June 2016.
''Tregea Hill''
Tregea Hill ({{gbmapping|SW648454}}) (also known as Western Hill) is the site of a possible promontory fort on the headland overlooking the village and former port of Portreath. Tregea was recorded in 1205 as Trege possibly meaning ″homestead of the bank or hedge″. The headland is enclosed by an earthen bank approximately 0.75 m high, and 1.5 m wide at the base, partly eroded by the sea.{{cite web|title=Tregea Hill|url=http://www.pastscape.org/hob.aspx?hob_id=426077&sort=4&search=exact&criteria=Tregea%20Hill&rational=q&recordsperpage=10|work=Pastscapes|publisher=English Heritage|accessdate=1 November 2012}}
Crane Castle
Crane Castle ({{gbmapping|SW631440}}) is on Carvannel Downs in the parish of Illogan. It is named or described in records in 1530, and again in 1635. The antiquarian William Borlase visited and described the site in the mid–18th century.{{cite book|last=Borlase|first=William|title=The Antiquities of Cornwall|year=1758|publisher=E & W Books|location=London|edition=1973 Reprint of Second}} Much of the cliff has eroded but a double rampart and ditches survive, being {{convert|85|m|ft|1|abbr=on}} and {{convert|71|m|ft|1|abbr=on}} in length. The ramparts average {{convert|2.3|m|ft|1|abbr=on}} in height and the ditch is up to {{convert|2|m|ft|1|abbr=on}} deep and {{convert|1.5|m|ft|1|abbr=on}} wide.{{cite web|title=Crane Castle|url=http://www.pastscape.org/hob.aspx?hob_id=426191&sort=4&search=exact&criteria=crane%20castle&rational=q&recordsperpage=10|work=Pastscape|publisher=English Heritage|accessdate=31 October 2012}} Small scale excavations in 2012 revealed the base of the inner ditch, {{convert|5.5|m|ft|1|abbr=on}} below the (contemporary) top of the rampart. The outer ditch was cut {{convert|1.5|m|ft|1|abbr=on}} into the bedrock. Ditch fill of quartz suggested an attempt to impress observers from the landward side. The narrow area between the ditches and steepness of the bands was thought to suggest a ″killing zone″, where attackers who overran the outer rampart, could be entrapped. The only find was the rim of a finely made bottle from the Roman period, probably imported from Gaul.{{cite journal|last1=Gossip|first1=James|title=Crane Castle, an Iron Age Promontory Fort|journal=Cornwall Archaeological Society Newsletter|date=October 2012|issue=130|pages=2–3|url=http://www.cornisharchaeology.org.uk/index_htm_files/NL%20130.pdf|accessdate=13 July 2014|url-status=dead|archiveurl=https://web.archive.org/web/20140714162942/http://www.cornisharchaeology.org.uk/index_htm_files/NL%20130.pdf|archivedate=14 July 2014}}
Gurnard's Head
Image:Gurnards head cornwall 01.jpg
Gurnard's Head ({{langx|kw|Ynyal}}, meaning desolate one) ({{gbmapping|SW431388}}) is a multivallate hillfort in the parish of Zennor and is one of only three to be excavated in Cornwall – the others being Maen Castle and Trevelgue Head. The inner rampart is the largest being over 5 m wide at the base and up to 2 m high although it was probably much higher as there is fallen masonry nearby. On the landward side there is an earthen bank with ditches on each side. Sixteen huts on the eastern side, sheltered from the prevailing wind show up as shallow scoops. Three were excavated (one partially) with few finds. Exact dating was not possible but the finds of an iron knife and iron buckle, spindle whorls, rubbing stone and pottery sherds indicate the middle second century BC for the initial occupation. The site is owned by the National Trust and is within the Aire Point to Carrick Du Site of Special Scientific Interest.
Bosigran
Bosigran Castle ({{gbmapping|SW415371}}) is an Ancient Monument within the parish of Zennor and owned by the National Trust. The cliff castle at Gurnard's Head is within sight to the east. The headland is cut off by a stone wall up to 1.6 m high with a blocked central entrance. There is no external ditch and no evidence of hut circles or occupation.{{cite web|title=Bosigran Castle|url=http://www.pastscape.org.uk/hob.aspx?hob_id=423566&sort=2&type=&typeselect=c&rational=a&class1=None&period=None&county=1306804&district=None&parish=None&place=bosigran&recordsperpage=10&source=text&rtype=&rnumber=|work=Pastscapes|publisher=English Heritage|accessdate=7 December 2012}}
Henry Jenner suggested Bosigran may mean {{gloss|the Dwelling of Igerna}}, the mother of King Arthur in Arthurian legend. Jenner also noted its proximity to Bosworlas (in St Just parish) {{gloss|the Dwelling of Gorlois}}, Igraine's husband in the Historia Regum Britanniae,{{cite journal | journal=Annual Report of the Royal Cornwall Polytechnic Society | title=Castle-an-Dinas and King Arthur | first=Henry | last=Jenner | authorlink=Henry Jenner | pages=100–101 | url=https://archive.org/details/annualreport04royauoft/page/100/mode/2up | year=1922 | volume=4 | series=New Series | publication-place=Plymouth and Falmouth }} who he believed was a real petty-chief in fifth or sixth century Dumnonia.{{cite journal | journal=Annual Report of the Royal Cornwall Polytechnic Society | title=The Royal House of Damnonia | first=Henry | last=Jenner | authorlink=Henry Jenner | page=139 | url=https://archive.org/details/annualreport04royauoft/page/138/mode/2up | year=1922 | volume=4 | series=New Series | publication-place=Plymouth and Falmouth }}
Kenidjack
File:View of Kenidjack Castle from the SW Coastal Path - geograph.org.uk - 780935.jpg
Kenidjack Castle ({{gbmapping|SW355327}}) is a multivallate hillfort in the parish of St Just. Two sets of triple ramparts with outer ditches have been built on the north east and south west sides. The northern ramparts are the best preserved and show the remains of stone revetting, with the inner one almost wholly built of stone. The outermost rampart of the southern set has been lost through erosion and landslip. Shallow hollows and scoops within the headland may be signs of hut circles or mining activity.{{cite web|title=Kenidjack Castle|url=http://www.pastscape.org/hob.aspx?hob_id=421757&sort=2&type=&typeselect=c&rational=a&class1=None&period=None&county=1306804&district=None&parish=None&place=kenidjack&recordsperpage=10&source=text&rtype=&rnumber=|work=Pastscapes|publisher=English Heritage|accessdate=7 December 2012|url-status=dead|archiveurl=https://archive.today/20130415144013/http://www.pastscape.org/hob.aspx?hob_id=421757&sort=2&type=&typeselect=c&rational=a&class1=None&period=None&county=1306804&district=None&parish=None&place=kenidjack&recordsperpage=10&source=text&rtype=&rnumber=|archivedate=15 April 2013}}
''Cape Cornwall''
William Borlase, in the 1870s, recorded the traces of a bank and ditch of what he identified as a likely cliff castle on Cape Cornwall ({{gbmapping|SW349319}}). A survey in 1960 identified only a possible ridge within the field, at the narrowest point on the neck adjoining the headland. English Heritage conclude that this was probably not the site of a fort or cliff castle.{{cite web|title=Cape Cornwall|url=http://www.pastscape.org/hob.aspx?hob_id=421618&sort=2&type=&typeselect=c&rational=a&class1=None&period=None&county=1306804&district=None&parish=None&place=cape%20cornwall&recordsperpage=10&source=text&rtype=&rnumber=|work=Pastscapes|publisher=English Heritage|accessdate=7 December 2012}}
Maen Castle
image:Entrance to Maen Castle - geograph.org.uk - 943043.jpg
Maen Castle ({{langx|kw|Maen, Men or Mayon}}, stone castle) ({{gbmapping|SW348257}}) is an Ancient Monument owned by the National Trust, and is situated between Sennen Cove and Land's End, within the parish of Sennen. The South West Coast Path passes the entrance. A ditch and external bank cuts off a small headland. It is thought to be one of the earliest cliff castles.{{cite book|last=Johnson|first=Nicholas|title=Cornwall's Archaeological Heritage|year=1990|publisher=Cornwall Archaeological Unit|location=Truro|isbn=0906294215|last2=Rose|first2= Peter}}
The West Cornwall Field Club excavated the site in 1939 and again in 1948–9. Three hundred pottery sherds, mainly from one habitation site, were dated to between 800 and 400 BC. A 1986 National Trust survey found a ″kink″ in the line of the wall, which showed that the wall was built into an earlier field system, thought to be Bronze Age or early Iron Age.{{cite web|title=Maen Castle|url=http://www.pastscape.org.uk/hob.aspx?hob_id=421208|work=National Monuments Record|publisher=English Heritage|accessdate=25 September 2012}}
''Carn Les Boel''
File:Cliff-castle at Carn Les Boel - geograph.org.uk - 851439.jpg
Carn Les Boel ({{gbmapping|SW357232}}) is an Ancient Monument situated between Nanjizal and Gwennap Head in the parish of St Levan. The South West Coast Path passes nearby. Its identification as a cliff castle or promontory fort is insecure. One of its banks may date to the enclosure of Higher Bosistow Cliff in the 19th century; apart from a gap of 5 m at Zawn Peggy, where the cliff has eroded, the bank and ditch follow the line of the cliff northwards for a further 300 m.{{cite web|title=Carn Les Boel|url=http://www.pastscape.org.uk/hob.aspx?hob_id=421257&sort=4&search=exact&criteria=carn%20les%20boel&rational=q&recordsperpage=10|work=National Monuments Record|publisher=English Heritage|accessdate=25 September 2012}}{{cite web|title=Carn Lês Boel – Promontory Fort|url=http://www.megalithic.co.uk/article.php?sid=19834|work=Pastscape|publisher=English Heritage|accessdate=1 November 2012}}
Treryn Dinas
Treryn Dinas is a promontory fort and scheduled monument near Treen, on the Penwith peninsula. It is owned by the National Trust.[https://historicengland.org.uk/listing/the-list/list-entry/1006733 Promontory fort known as Treryn Dinas] Historic England, accessed 20 June 2016. Its landward side has widely spaced defensive earthworks; the innermost rampart, which crosses the narrowest part of the peninsula neck, is up to {{convert|2|m|ft}} high. Beyond it are two low curving ramparts, and a massive outer rampart, up to {{convert|6.1|m|ft}} high, with a ditch on its northern side and a causewayed entrance. The Logan Rock sits seawards within the fort, above the cliffs.[https://heritagerecords.nationaltrust.org.uk/HBSMR/MonRecord.aspx?uid=MNA107333 Treryn Dinas Cliff Castle, Treen and Rospletha Cliffs Penberth Valley and Cove, St Levan] National Trust, accessed 20 June 2016.[http://www.cornwalltour.co.uk/treryn_dinas.html Treryn Dinas and Logan Rock] Cornwall Tour, accessed 20 June 2016.
St Michael's Mount
A complex of earthworks on St Michael's Mount ({{gbmapping|SW514298}}) are considered to be the ramparts of a cliff castle. They were discovered in 1992 on the eastern side of the Mount and separate the granite outcrop from the harbour area.{{cite book|last=Herring|title=St Michael's Mount.

Lankidden
Lankidden ({{gbmapping|SW755168}}) is a univallate cliff castle between Coverack and Kennack Sands on the Lizard peninsula. The rampart is 100 m long and up to 4 m high and the ditch is 0.5 m deep. To the west, part of the rampart and ditch have been lost to erosion.{{cite web|last=Lankidden|title=Lankidden|url=http://www.pastscape.org.uk/hob.aspx?hob_id=426464&sort=2&type=&typeselect=c&rational=a&class1=None&period=None&county=None&district=None&parish=None&place=lankidden&recordsperpage=10&source=text&rtype=&rnumber=|work=Pastscape|publisher=English Heritage|accessdate=11 December 2012}}
Rame Head
Rame Head ({{gbmapping|SX41794828}}) is a promontory fort defined by steep cliffs on three sides and at the northeast, a narrow neck of land connects it to the mainland. Here it is protected by a deep outer ditch with an earth and stone rampart and a central entrance. The rampart has been built over by 20th century concrete defensive structures, now demolished. Some flints have been found inside. At the top of rising ground at the centre of the fort is a small medieval chapel.{{cite web|title=Promontory fort, medieval chapel of St Michael's and Second World War radar station at Rame Head |url=https://historicengland.org.uk/listing/the-list/list-entry/1004510?section=official-listing |website =historicengland.org.uk |publisher=Historic England |accessdate =18 December 2021}}
