The Chandler Armory building in Chandler, Oklahoma is an Art Deco military building which now houses the Route 66 Interpretive Center, a museum devoted to understanding the construction and history of U.S. Route 66. The structure is apparently notable for having the only brick outhouse in Oklahoma, complete with original French fixture. It was built of local red sandstone by the Works Progress Administration between 1935 and 1937 as a home for Battery F, Second Battalion of the 160th Field Artillery of the Oklahoma National Guard, 45th Infantry division, and after vacation by the military in 1971 was vacant until becoming the home of the museum in 2007. The building was added to the National Register of Historic Places in 1992.
