Williamsport Armory
Why it's listed
Built in three phases between 1927 and 1937, the Williamsport Armory occupies a sizable lot in the city and is laid out in a T-shaped plan. The two-story brick administrative block, completed in 1930, carries stone panels, brick buttresses and eight-light and sixteen-light casement windows, while the drill hall added in 1937 has a steel Pratt truss roof spanning about 5,400 square feet. A brick stable and gun shed dating from 1927 sit directly east of the main building. The complex served as a home for Company D, 107th Field Artillery, of the Pennsylvania National Guard. It is regarded as a representative example of the T-plan armories built across Pennsylvania, and its surviving interior spaces, including the drill hall, rifle range and offices, reflect how these facilities functioned for the state's guard units.
Significance in brief: The armory has been an integral part of the Pennsylvania National Guard and is representative of the T-plan armories built in Pennsylvania, of which the nomination counts thirty-seven. It was constructed for Company D, 107th Field Artillery, in three phases between 1927 and 1937, and it is regarded as a member of the State Armory Building property type. Its architecture and military role both contribute to its significance at the state level.

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.
