E. Barrett Prettyman U.S. Courthouse and William B. Bryant Annex

The E. Barrett Prettyman Federal Courthouse was built from 1948 to 1952.  President Harry S. Truman laid the cornerstone on June 27, 1950, and the courthouse opened in November of 1952. The courthouse is listed in the National Register of Historic Places and is a contributing property to the Pennsylvania Avenue Historic Site.  In 1997 the courthouse was renamed after the Honorable E. Barret Prettyman, former Chief Judge of the U.S. Court of Appeals for the District of Columbia Circuit.

The E. Barrett Prettyman U.S. Courthouse was expanded in 2006 with the William B. Bryant Annex.  The annex was named after the Honorable William Benson Bryant, who was the first African American to serve as Chief Judge of the U.S. District Court for the District of Columbia.  The annex houses courtrooms, office space, and the rotunda contains a cafeteria on the ground floor.
