Tonawanda Armory

The Tonawanda Armory is a historic armory originally built for the 25th Separate Company of the New York National Guard, and located in the city of Tonawanda in Erie County, New York. It is a brick and stone castle-like structure built in 1897, designed to be reminiscent of medieval military structures in Europe. It was designed by State architect of New York Isaac G. Perry.

It consists of a two-story, hip-roofed administration building with an attached $1 1/2$-story, gable-roofed drill shed, spanning open space of 30000 sqft. The building features a five-story octagonal tower at the southwest corner and a two-story round tower at the northwest corner.

It was listed on the National Register of Historic Places in 1994. It is now privately owned and available for rental or tours.
