Unity Temple

Eleven members of the Union Church—a liberal Protestant congregation in Oak Park, a village in the suburbs of Chicago, Illinois—met on January 25, 1871, to discuss the formation of a new congregation.{{harvnb|Sokol|2008|ps=.|page=6 }}{{harvnb|Oak Leaves April 27, 1907|ps=.|page=100 }} E.

Work on the new church began in early 1871, and the basement was finished later that year. A consecration ceremony was held on August 11, 1872. In its early years, the congregation was composed of Universalists and Unitarians. As such, the church went through several pastors in its first decade. In 1882, some of the congregation's Universalist members formed a sub-congregation affiliated with the Universalist Church of America; the congregation at large remained unaffiliated with any denomination.{{harvnb|Sokol|2008|ps=.|page=9 }}{{harvnb|Oak Leaves April 27, 1907|ps=.|page=101 }} After going through six pastors in fifteen years, the church selected Augusta Jane Chapin as its pastor in 1886.{{Cite news |date=May 2, 1886 |title=Suburban Matters |via=newspapers.com |url=https://www.newspapers.com/article/the-inter-ocean-suburban-matters/164112363/ |access-date=January 28, 2025 |work=The Inter Ocean |pages=14 }} During Chapin's tenure, Anna Jones Wright, the mother of the architect Frank Lloyd Wright, joined the congregation.{{harvnb|Sokol|2008|ps=.|pages=10–11 }}

The bases of the columns are stepped inward, while the capitals are stepped outward, supporting the cantilevered roofs above. The juxtaposition of the columns, and the roofs above them, may have been an allusion to older classical-style and religious buildings with pillars. The facade is topped by square and rectangular copings. In the 2010s, lighting was installed on the ground outside the building.

Unlike contemporary churches, Unity Temple was designed without a spire, nor did it include typical church features such as a tower or an arched roof.{{Cite news |last=Rowley |first=Gordon E. |date=October 10, 1982 |title=Checking out what's Wright in Illinois |via=newspapers.com |url=https://www.newspapers.com/article/the-san-francisco-examiner-checking-out/164866859/ |access-date=February 6, 2025 |work=The San Francisco Examiner |pages=95 }} At the time of construction, church spires were increasingly outdated and were vulnerable to lightning strikes.{{harvnb|Siry|1996|ps=.|page=77 }} The temple is instead topped by 14, 16, or 17 flat roofs.

The auditorium roof's eaves extend {{Convert|5|ft}} outward from the facade's columns,{{harvnb|Siry|1996|ps=.|page=155 }} overhanging the adjacent lawns and paths. The writer Neil Levine wrote that the cantilevered roofs created the impression that the interiors were being directed outward.{{harvnb|Levine|1996|ps=.|page=41 }} The edges of each roof are twice as thick as the rest of the roof, creating a low parapet wall, while the eaves contrast with the facade's thick base.

Wright described Unity Temple's interior as reflecting "the reality of the building—the space in which we live and not the walls and the roof". The foundations and columns are made of conventional concrete; the floor slabs are made of cinder concrete, in which coal cinders are embedded into the cement. The superstructure also uses steel beams, which are entirely covered with concrete. The interior was more colorful than the gray exterior, in part because of the windows. The walls are made of plaster, which is covered with an aggregate of sand, cement, and putty; a sealant was added to this aggregate, and the sealant was painted.{{harvnb|Siry|1996|ps=.|page=165 }} The interiors are also decorated with wooden boards, which not only articulate (or stylize) the interiors,{{harvnb|McCarter et al|1997|ps=.|page=19 }} but also conceal electrical wires.{{harvnb|Siry|1996|ps=.|page=164 }} Joseph Siry described the decorations as "a poetic invention that sprang from Wright's own imagination", while Neil Levine wrote that the decorations highlighted "space and depth, rather than mass and volume".{{harvnb|Levine|1996|ps=.|page=46 }} Wright also included high ceilings 'for the contemplation for the soul", as Oak Leaves described it.{{cite web |date=June 18, 1969 |title=Concert in Unity Temple to honor Wright heritage |url=https://riverforest.advantage-preservation.com/viewer/?i=f&d=01011967-12311969&e=unity%20temple&m=between&ord=e1&fn=forest_leaves_usa_illinois_oak_park_19690618_english_6&df=1&dt=10 |access-date=February 6, 2025 |work=Oak Leaves |page=6 |via=River Forest Public Library }}

An entrance pavilion, measuring {{Convert|24|by|32|ft}} across, connects the auditorium and Unity House.

The north wall of the foyer is decorated with wooden slats and was initially designed as a hidden exit from the auditorium, without any doorknobs or visible hinges.

The foyer's west and east walls each contain a bank of six doors measuring {{convert|20|ft}} wide, with art-glass panes; the west doors form the main entrance. The south wall has a glass partition, behind which Unity House's fireplace can be seen. A pastor's study is located within the second floor of the pavilion and is directly connected to both the auditorium and Unity House.{{harvnb|McCarter et al|1997|ps=.|page=22 }}

Wright wanted congregants to circulate around the auditorium's perimeter, rather than entering it from a central aisle,{{harvnb|Siry|1996|ps=.|page=104 }} and he wanted the piers to draw visitors' attention inward. The piers are connected by "cloisters", hallways {{Convert|4|ft}} beneath the auditorium's main floor.{{harvnb|Levine|1996|ps=.|page=43 }} According to Wright, this preserved the auditorium's "quiet and dignity" by allowing people to circulate around the room unnoticed.{{harvnb|McCarter et al|1997|ps=.|pages=17–18 }} The bases of the piers contain small anterooms, and staircases ascend to the main floor and balcony level. The piers also include pipes and ducts for heating and ventilation. The piers are decorated with wooden strips that meet at right angles.{{harvnb|Siry|1996|ps=.|page=180 }}

At the center of the cross is a square measuring {{convert|33|ft}} on each side,{{harvnb|Siry|1996|ps=.|page=160 }} with a pulpit at the center. The pulpit is arranged so it is no farther than {{Convert|45|ft}} or {{Convert|75|ft}} from any seat. In front of the pulpit is a railing with wooden boards across its surface and a wooden coping at its top. The center of the railing, in front of the pulpit's lectern, is slightly raised. There is a bench behind the railing, as well as lamps to either side.{{harvnb|Siry|1996|ps=.|page=186 }} The southern wall contains a choir loft directly above the auditorium's entrance, which extends to the balcony level.

According to architectural critic Blair Kamin, the layout makes it so that "one enters as an individual and leaves as a member of a community". The exit doors are normally closed during services. Since 2017, there has been a video screen behind the pulpit.

The balcony is about {{convert|13.5|ft}} or two units above the ground and also surrounds the auditorium on three sides. The balcony has 153 seats in total, which are more steeply raked than those on the main level. The balcony is illuminated by spherical lamps, and there are wooden bands on the balcony's railings and on the soffit along the balcony's underside. The architectural historian Robert Twombly wrote that the balconies gave the auditorium an intimate feel while allowing visitors to feel like they were part of a larger "majestic whole".

The decorations in the auditorium, such as the windows and chandeliers, are generally designed with cruciform motifs, recalling its overall shape. Generally, the lower part of the room is painted in darker shades of yellow and green, while the upper part is painted in lighter shades. The baseboards and the piers' pedestals were left unpainted, since Wright anticipated that this would give the room a more somber ambiance. Natural light is provided through ceiling skylights and clerestories, as well as the narrow slit windows. According to Wright, the windows were intended "to get a sense of a happy cloudless day into the room". Other than the slit windows and the door to the foyer, the lower part of the auditorium has no openings. Wright had designed planters or urns for the auditorium, but church officials refused to accept them.{{harvnb|Siry|1996|ps=|pages=184–185}}; {{harvnb|Sokol|2008|ps=.|pages=132–135 }} The auditorium also has several hardwood chairs, built in 2003 to replace the original Wright–designed chairs.

The auditorium's ceiling is {{convert|27|ft}} high.{{harvnb|Siry|1996|ps=.|page=124 }} The center of the ceiling is topped by amber skylights, which are surrounded by bands of wood. The roof is supported by solid concrete beams oriented east–west, while the north–south beams are of hollow concrete.{{harvnb|Siry|1996|ps=.|page=172 }} Inset within this grid of beams are 25 square skylight panels. Each panel measures {{Convert|4+5/6|ft}} across, with 83 pieces of glass, and is decorated with a fork-shaped motif pointing in one of the four cardinal directions.{{harvnb|Siry|1996|ps=.|pages=174–175 }} A New York Times article likened the skylights' designs to Piet Mondrian's artwork. The space is also illuminated by overhanging spherical chandeliers flanked by cubic lamps,{{harvnb|Siry|1996|ps=.|pages=185–186 }} and the perimeter of the ceiling is made of oak boards.

The interior of Unity House is painted in various shades of green, yellow, and brown. Unity House's primary interior space measures about {{convert|82+5/6|by|27+1/6|ft}} across, corresponding to approximately 12 by 4 units. There is a square hall at the center, measuring about {{Convert|30|ft}} or {{Convert|33+5/6|ft}} on each side. There are balconies to the west and east of the central hall, on the same story as the auditorium's lower seating level. The balconies are supported by I-beams and contain small columns with wooden sconces, in addition to railings with wood strips. The columns have vertical wood strips along their shafts and horizontal wood strips at their capitals. The spaces under each balcony are illuminated by spherical lamps.{{harvnb|Siry|1996|ps=.|pages=161–162 }} The balconies and the spaces beneath them were originally used as classrooms.

There are square closets at each corner of Unity House's main room, measuring about 1 unit wide. On the southern wall of the central hall is a recess with a fireplace measuring about {{Convert|13+1/6|ft}} wide; this feature recalled many of Wright's residential designs, which also had central fireplaces.{{cite web |last=Gibson |first=Eleanor |date=June 12, 2017 |title=Frank Lloyd Wright's Unity Temple was the "first expression" of modern architecture |url=https://www.dezeen.com/2017/06/12/unity-temple-frank-lloyd-wright-chicago-oak-park-modern-architecture-150th-birthday/ |access-date=January 31, 2025 |website=Dezeen }} On the northern wall, there are three casement windows facing the pastor's study.

Unity House primarily receives natural light from skylights in the ceiling. The roof trusses are supported by eight columns arranged in a 2×4 grid. The ceiling is divided into rectangular coffers measuring {{convert|15|by|4.5|ft|adj=off}} across. Each coffer has a skylight with four glass panes, which are either opaque or tinted in various shades of yellow, green, and brown. There are seven skylights in total, all of which are surrounded by wood strips. Rectangular and square motifs, reminiscent of the floor plans, are used in the skylights.

Unity Temple originally had a coal-fired steam boiler, in addition to concrete ducts that were supposed to distribute heat.{{harvnb|Sokol|2008|ps=.|page=137 }} The ducts proved ineffective at carrying air, and as such, steam radiators were installed shortly after the temple was finished. A hot-water system was also installed within half a year of the temple's completion; it remained in use through the 21st century. The coal-fired boiler was replaced with an oil-fired boiler in the early 20th century, and a gas generator was added later in the century. Since the 2010s, the church has been heated by a geothermal heating system,{{cite web |last=Lydersen |first=Kari |date=October 15, 2018 |title=Geothermal and the city: Utilities and industry push installations in Chicago |url=https://energynews.us/2018/10/15/geothermal-and-the-city-utilities-and-industry-push-installations-in-chicago/ |access-date=January 27, 2025 |website=Energy News Network }} which consists of nine {{Convert|500|ft|4=-deep|adj=mid}} wells on the lawn just north of the church.

When Unity Temple was completed, it differed significantly from other local churches' designs. Wright considered Unity Temple to be his first completed concrete-building design,{{cite news |date=October 4, 1953 |title=Frank Lloyd Wright and His Art |work=The New York Times |issn=0362-4331 |pages=SM26 |id={{ProQuest|112564807}} |postscript=none}}; {{Cite magazine |last=Del Campo |first=Santiago |date=Apr 1954 |title=An Afternoon With Frank Lloyd Wright |magazine=Americas |page=11 |volume=6 |issue=4 |id={{ProQuest|1797186012}} }} and it was reportedly the first major reinforced-concrete building constructed in the U.S.{{Cite news |last=Gapp |first=Paul |date=March 13, 1992 |title=Deity of U.S. Design |work=Sun Sentinel |page=3E |id={{ProQuest|388948852}} }} The temple is also an early example of a building with an exposed-concrete facade, contrasting with earlier concrete structures in Europe, whose surfaces were typically concealed behind cladding. Paul Gapp of the Chicago Tribune wrote retrospectively that Wright's use of concrete was "a daring risk at the time".

Unity Temple has been cited as an early example of modern architecture,{{Cite news |date=May 9, 1939 |title=The American "Pioneer" Architect |work=The Manchester Guardian |page=10 |id={{ProQuest|484618839}} }} with Wright citing it as his first modern-style building.

Upon the temple's completion, images of the auditorium were published in Inland Architect and News Record magazine. Local newspaper Oak Leaves called it "the most radical departure in traditional church architecture ever attempted", and the same newspaper said the "severe simplicity of the exterior of the building [...] gives one little hint of the beauty of the interior". A writer for the Chicago Daily Tribune said Unity Temple's modern design represented "the present, the twentieth century, the modern spirit, thought, faith, the modern freedom, the modern ideal".{{cite news |last=Krecker |first=Ada May |date=May 16, 1909 |title=A Church of Which Oak Park Is Proud |work=Chicago Daily Tribune |issn=1085-6706 |page=H4 |id={{ProQuest|173528161}} }} Architectural Record praised the acoustics as "not sonorous and [...] only slightly reverberant".{{cite web |last=Niedert |first=Kathy |date=January 28, 1976 |title='Music's sound is perfect here' |url=https://riverforest.advantage-preservation.com/viewer/?i=f&d=01011975-12311976&e=unity%20temple&m=between&ord=e1&fn=forest_leaves_usa_illinois_oak_park_19760128_english_47&df=1&dt=10 |access-date=February 6, 2025 |work=Oak Leaves |page=47 |via=River Forest Public Library }} Conversely, Winthrop Kendall regarded the building as unattractive, "without a vine or a tree to relieve its massive monotony",{{Cite news |date=November 29, 1909 |title=Defends the Architecture of Churches in Oak Park |via=newspapers.com |url=https://www.newspapers.com/article/chicago-tribune-defends-the-architecture/164303510/ |access-date=January 30, 2025 |work=Chicago Tribune |issn=1085-6706 |pages=6 }} and disappointed congregants likened the temple to a Mayan handball court.{{Cite news |last=Goodman |first=Walter |date=November 10, 1998 |title=Television Review; A Visionary's Dreams, Disguised as Buildings, Altered the Landscape |url=https://www.nytimes.com/1998/11/10/movies/television-review-visionary-s-dreams-disguised-buildings-altered-landscape.html |access-date=February 7, 2025 |work=The New York Times |issn=0362-4331 |language=en-US }}

A St. Louis Post-Dispatch article in 1961 said Unity Temple still "looks quite fresh and contemporary today", and The Buffalo News likened the building to a "visiting spaceship" in 1981,{{Cite news |last=Bull |first=John V.

After the auditorium's interior restoration was completed in the 1980s, a Boston Globe editor said the auditorium was "almost as shocking as the restoration of the Sistine Chapel".{{Cite news |last=Campbell |first=Robert |date=May 5, 1987 |title=Crumbling National Treasures It's Time to Restore Frank Lloyd Wright's Houses |page=67 |id={{ProQuest|294429166}} }} The architectural critic Paul Goldberger perceived Unity Temple as representing "a kind of symbolic gathering and communal presence, monumental dignity in a public place",{{cite web |date=November 12, 2018 |title=Unity Temple |url=https://www.pbs.org/kenburns/frank-lloyd-wright/unity |access-date=February 8, 2025 |publisher=PBS }} calling it one of "the greatest religious structures" of the 20th century.{{Cite news |last=Goldberger |first=Paul |date=December 26, 1982 |title=Housing for the Spirit |url=https://www.nytimes.com/1982/12/26/books/housing-for-the-spirit.html |access-date=February 8, 2025 |work=The New York Times |issn=0362-4331 |language=en-US }}

A writer for The Chronicle of Higher Education in 1996 contrasted Unity Temple's "blocky" massing with the low-roofed design of Robie House on Chicago's South Side. David M. Sokol, in his 2008 book The Noble Room, wrote that the temple's "majesty and importance" was partially derived from the fact that it was not arranged as typical church buildings had been. A writer for The Washington Post wrote that the building may have been one of Wright's favorite designs because it was "imposing yet elegant". After the temple's renovation was finished in 2017, a Curbed writer said the building's imposing concrete facade "belies what's inside", while a Chicago Tribune writer called the auditorium "magnificent sanctuary noted for its high skylights of amber-tinted leaded glass". Blair Kamin wrote for The Wall Street Journal in 2025 that the temple's exterior was "monolithic, not monotonous" because of its use of textured concrete and geometric motifs, while "the sanctuary is as serene as architecture gets".

Unity Temple has also received architectural accolades. In 1959, the American Institute of Architects (AIA) deemed Unity Temple as one of 17 buildings designed by Wright that merited the highest levels of architectural preservation.{{cite web |date=February 22, 2017 |title=Seventeen Buildings Honored by the American Institute of Architects |url=http://www.wrightontheweb.net/his-works/17-buildings/ |publisher=Wright on the Web }}{{cite web |last=Board of Directors, American Institute of Architecture |title=Seventeen Buildings Worthy of Preservation |url=http://communities.aia.org/sites/hdoaa/wiki/AIA%20scans/T-Z/17%20FLW%20buildings.pdf |access-date=November 2, 2012 |publisher=American Institute of Architects }} A 1991 poll in Architectural Record magazine ranked Unity Temple as one of the 10 most significant buildings in the United States from the previous century.
