U.S. Department of Treasury: The Department of Treasury Building is open for public tours on Saturday mornings, with reservations available only through Congressional offices. They are offering tours for the first time since the events of September 11, 2001, after which tours were suspended and extensive renovations were made to the building. Like its immediate neighbor, the White House, the Treasury Department has remained on its original Pennsylvania Avenue site since 1800, when the federal government permanently moved to Washington. The present building was begun in 1836; over time the Treasury Department has assembled an impressive collection of artifacts, works of art and furniture, many of which continue to serve their intended purpose and are exhibited in restored historic rooms, suites and offices. The tours will focus on the history of the Treasury and the architectural history of the building, highlighting the restored spaces, including the Salmon Chase Suite, the Andrew Johnson Suite, the West wing gilded monumental dome and lobby and the Cash Room, which was the scene of Ulysses S. Grant’s inaugural reception.

Pentagon: Located across the 14th Street Bridge in Virginia. Public tours are available Monday through Friday starting at 9:30 a.m. and leave every 30 minutes. An adult must accompany visitors under 16 years of age. Reservations are required for groups of nine or more and must be made at least two weeks in advance. Requests are made through Congressional Offices.
