In the 1940s a spare room on the fifth floor of the United States Supreme Court building was converted to a workout area. Later, wooden backboards and baskets were added. Today, the space is a basketball court for clerks, off-duty police officers and other Supreme Court employees.
While the space is smaller than regulation, it has drawn noteworthy players, like Supreme Court Justice Byron White and Chief Justice William H. Rehnquist. A sign is posted reminding players to refrain from shooting hoops on a court day to avoid disrupting Supreme Court proceedings.
The court is not open to the public.
