Mansfield Armory
Why it's listed
Built in 1938 as a Works Progress Administration project, the brick Mansfield Armory stands on a flat lot in Mansfield, Tioga County. It measures about 96 by 140 feet and is rectangular in plan, with a one-story section surrounding a central drill hall that rises higher and is covered by an arched roof. Its exterior features include a parapet with stone coping, a corbeled cornice, decorative brickwork, four-over-four sash windows, and overhead garage doors. The main south elevation is divided into thirds by two wooden double-door entrances. The building was designed by Thomas H. Atherton of Wilkes-Barre, who designed eight armories in eastern Pennsylvania. It was built for the 108th Ambulance Company, 103rd Medical Regiment of the Pennsylvania National Guard. The armory is considered unusual for its raised drill hall, while its interior rooms, including the drill hall, locker room, offices, kitchen, and day room, are typical of Pennsylvania armories. The nomination regards its integrity as very good despite replaced doors and a drop ceiling.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
