The original building was designed by Will Price and M H. McLanahan in 1908 as the Armory for "Company H of the 6th Infantry Regiment" of the Pennsylvania National Guard. The 2 story structure is primarily constructed of stone and steel and has a basement. The "structure's intended military use is expressed by its heavily buttressed walls, broken battlements, and low flanking towers," according to a plaque affixed to the building by the Media Borough Council in 1984. Company H served in Mexican Border Expedition, and re-designated as "Company H, 111th Infantry, 28th Infantry Division", in France in World War I, and as "Company M," in the South Pacific in World War II.
