The Old Post Office Tower is located in the same building as the current Waldorf Astoria Hotel. The building was built between 1892 and 1899 for the US Post Office Department Headquarters and as the local post office.
The building is the second largest structure in Washington DC (the largest is the Washington Monument).
After entering the building and the security/bag check (no food allowed inside) we entered a hallway with exhibits on the history of the building and the U.S. Postal Service. The hallway led to an elevator which took us up. We needed to change elevators to reach the actual tower.
When we entered the observation deck we saw an old clock displayed in the center and glass windows on all sides of the room. Each direction had a posted map board with the names of the landmarks we could see. The National Parks guides were very helpful and shared knowledge and information about Washington D.C. in general and about the Post Office Tower.
