One gatehouse and three of the gateposts now stand at 15th Street and Constitution Avenue within the President's Park South (PPS) historic district north of the National Mall.

The gatehouses stood at the base of Capitol Hill on the west side at a carriage entrance to the grounds.

[2] The gatehouses were removed from the Capitol grounds in 1874 as part of landscaping renovations designed by Frederick Law Olmsted.

[5] Four of the original Bullfinch gateposts from the former fence around the Capitol grounds were moved to Constitution Avenue at the same time as the gatehouses.

The east gatehouse bears two high water marks carved into the stone to commemorate flooding in 1877 and 1881.
