Old Post Office

The Old Post Office, listed on the National Register of Historic Places as the Old Post Office and Clock Tower, is located at 1100 Pennsylvania Avenue NW in Washington, D.C. It is a contributing property to the Pennsylvania Avenue National Historic Site.It succeeded an earlier 1839 edifice–the General Post Office–a building in the Classical Revival style, which was expanded in 1866 on F Street NW. This building later housed the Tariff Commission and several other agencies.

The Old Post Office construction was begun in 1892 and completed in 1899. The building is an example of Richardsonian Romanesque, part of the Romanesque Revival architecture of the 19th-century United States. Its bell tower is the third tallest structure in Washington, excluding radio towers.
