Old Post Office
The interior of the Old Post Office Building in Washington DC. Built in 1899, it was Washington's first "sky-scraper" at 12 stories tall. Despite being slated for demolition in the early 20th century, it was saved and renovated, and today is one of Washington's most popular attractions.
