John A. Wilson Building

The John A. Wilson District Building, popularly known simply as the Wilson Building, houses the municipal offices and chambers of the Mayor and the Council of the District of Columbia. Originally called the District Building, it was renamed in 1994 to commemorate former Council Chair John A. Wilson. Completed in 1908, during the administration of 26th President Theodore Roosevelt, the building is a contributing structure to the Pennsylvania Avenue National Historic Site.
The original site of the John A. Wilson Building was a streetcar power station that had been destroyed by a fire in 1897. With the "Public Building Act" of 1902, the United States Congress authorized $550,000 for the purchase of the property and an additional $1.5 million dollars for the construction of a new District municipal building. Previously, the D.C. government had been housed in the old District of Columbia City Hall, a historic neoclassical styled structure on Indiana Avenue, constructed 1822-1849 by George Hadfield.
