Visitors board the elevator that provides access to Old Post Office' clock tower, Saturday, April 26, 2014, in Washington. The National Park Service says the tower of the Old Post Office is closing for two years during renovations to the building. The tower will close May 1 and re-open in the spring of 2016. The 115-year-old federal building at the corner of 12th Street and Pennsylvania Avenue is scheduled to be converted into a mixed-use development including restaurants, a spa, conference space and a luxury hotel.
