Because it closes at 3, we only saw the outside. The exterior is worth the trip, however. Concrete was only used for industrial buildings, at the time the Temple was constructed (around 1900), Frank Lloyd Wright made a decision to make this building out of it. The almost windowless concrete exterior gives large flat planes that highlight the ornamentation under the overhanging eaves. Photographing a sign on the west side was problematic as the sun was shining straight on it. I'll have to photoshop my pictures of the place.
The Unity Temple is in stunning contrast to the Post Office across the street, which was Deco Federal style done by the WPA.
