Fort Clayton, Former military fort near Balboa, Panama

Fort Clayton is a former United States Army base northwest of Balboa, near the Panama Canal, in the former Canal Zone. Its long three-story buildings have cream-colored walls, dark red trim bands between floors, red-brown tiled roofs and a ground-floor row of dark arched openings; two tall palms stand in front, with a wooded hillside behind. Portions of the site overlook the Miraflores Locks.

Fort Clayton was one of the largest US Army bases inside the Panama Canal Zone, alongside Albrook and Howard, and was named for Colonel Bertram T. Clayton, a former quartermaster general of the Canal Zone department who died serving in World War I. It remained active until 1999, when it closed under the Torrijos-Carter Treaties; the headquarters of United States Army South operated there before moving to Fort Buchanan, Puerto Rico.

Fort Clayton is named after Colonel Bertram T. Clayton, the former quartermaster general of the Canal Zone department, who died serving his country in World War I. Today the former base hosts the Ciudad del Saber (City of Knowledge) and its schools, and its sports grounds include the home of the Panama national cricket team.

The site is accessible by public transportation and now houses Ciudad del Saber, featuring educational institutions, technology companies, and research centers. Daytime visits are possible, though some areas may have restricted access.

The base was named after Colonel Bertram T. Clayton, a former quartermaster general of the Canal Zone department, who died serving his country in World War I. The 534th Military Police Battalion stationed here helped patrol all Pacific-side military installations.
