Completed in 1837, it was designated a National Historic Landmark in 1971 for its exceptionally fine Greek Revival architecture.
Occupying a relatively narrow lot, its facade consists of a pair of fluted stone columns topped by Ionic capitals and set in antis beneath an entablature and iron crested parapet.
Behind the columns is a three-bay facade, with tall multipane windows flanking and rising above the center entrance.
The interior retains some original finishes, notably including Ionic columns and a domed ceiling.
Gideon Shryock, who was long thought to be its designer, apparently served as its construction superintendent.
