Built in 1899, and used as the city's main post office until 1914, the Old Post Office's clock tower offers panoramic views of Washington, D.C. At 315 feet tall, it's the third highest building in D.C. The tower also houses the Congress Bells, a Bicentennial gift from England and replica of those at London’s Westminster Abbey.
Today, the post office is used mostly as food court—we stop in often for Adam's favorite, Ben & Jerry's. But this past afternoon we decided to tour the clock tower and boy were we wowed. The clock tower offers one of the best views of the city and it was fascinating to learn about the history behind the bells and the building itself. It seems to be one of DC's less popular landmarks—but a must-see on my list.
