Currently undergoing some major renovations, the Old Post Office Pavilion is not the place to drop off a "Wish You Were Here!" postcard. This historic landmark was converted into a shopping destination in 1978 and is known for the stunning views from the observation deck as well as its rich history and prime location.
Residing in the heart of the city, the building is a national monument complete with a century-old clock tower and Bells of Congress.
