18th Separate Company Armory
Why it's listed
Built in 1895, this armory at 147 Warren Street in Glens Falls housed arms storage and a drill hall for the 18th Separate Company, New York National Guard. It is a rectangular building of pressed brick over a raised limestone foundation, with hipped slate roofs, a crenelated tower, deep-set windows with stone lintels, and an east entrance of two tall rounded brick arches beneath an arcaded gallery. Together these features give it a fortress-like look. Its design is attributed to state architect Isaac Perry, and it closely resembles his 1894 armory at Hornell. The Romanesque Revival qualities of mass, simple form and heavy stone detail were typical of 1890s civic architecture and suited the building's purpose. The local militia unit traces back to the Hughes Light Guard, organized in 1876. The armory is regarded as a well-preserved example of the state armories built in larger New York communities, and it still serves National Guard units today. A later brick garage is attached at the southeast corner.
Significance in brief: The nomination argues the armory is a well-preserved, intact example of the monumental state armories built in larger New York communities in the late nineteenth century. Its massive Romanesque Revival character reflects the civic buildings designed under state architect Isaac Perry. It also reflects the regional importance of Glens Falls, and it still serves its original function.

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.
