The Old Post Office Tower soars to 315 feet, making it third in height among the buildings of the nation's capital. The 270-foot observation level allows visitors an awe-inspiring view of the city and the area. Here also are the century old tower clock and the Bells of Congress. The latter were a Bicentennial gift from the Ditchley Foundation in England. Beneath the observation deck is the tower clock, now more than a century old.

From Memorial Day to Labor Day, the tower is open from 9 a.m. to 8 p.m., Monday through Saturday, except Thursdays when the tower closes at 7 p.m. for bell ringing practice. On Sundays and Federal Holidays, the tower is open from 10 a.m. to 6 p.m. From Labor Day to Memorial Day, the tower is open from 9 a.m. to 5 p.m., Monday through Saturday.
