U.S. Capitol Gatehouses and Gateposts
U.S. Capitol Gatehouses and Gateposts, Neoclassical gatehouses and stone posts in Constitution Avenue, Washington DC, United States
The sandstone gatehouses feature Tuscan order porches at their fronts with rough-coursed masonry walls on their sides and rear sections.
Charles Bulfinch designed these structures in 1828 to mark the entrances to the United States Capitol, before their relocation in 1874 during grounds renovation.
The gatehouses reflect the early 19th-century federal architectural style that influenced the development of Washington DC's governmental buildings.
Two gatehouses now stand at Constitution Avenue intersections with 15th and 17th Streets, while four additional posts are at the National Arboretum.
The east gatehouse contains carved markings indicating water levels from two major floods that occurred in 1877 and 1881.
