Its brick buildings in French Renaissance and Tudor Revival styles are regarded as the largest concentration of armory architecture nominated under the Pennsylvania National Guard Armories multiple property group. The buildings were designed by Harrisburg architect M. Edwin Green and Thomas H. Atherton, who also designed armories elsewhere in eastern Pennsylvania.","narrative":"Built mostly between 1929 and 1938 on a twenty-eight acre lot south of U.S. Route 22 and west of Fifteenth Street, this complex of brick buildings in French Renaissance and Tudor Revival styles served as the armory of the 104th Cavalry, a Pennsylvania National Guard unit. Stables Nos. 1 through 4 were erected between 1929 and 1932 to replace horses kept in rented and fire-prone buildings across the city, and the Gun Shed of 1930 sheltered horse-drawn caissons. The three-story Administration Building, completed in 1938 and designed by M. Edwin Green of Laurie and Green, has two wings joined by a drive-through archway flanked by conical-roofed towers. Thomas H. Atherton, a Wilkes Barre architect, designed the Warehouse and the stables. The post is regarded as the largest concentration of armory architecture in its multiple property group. After World War II the unit was mechanized, and vehicle storage buildings and a maintenance shop were added for its tanks and trucks.","period_of_significance":"1929-1939","architect_builder":"M.
