Geneva Armory is a historic National Guardarmory building located at Geneva in Ontario County, New York. The armory consists of a long, shallow, rectangular, five-story, hip-roofed administration building with an attached 1+1⁄2-story, rectangular gable-roofed drill shed. The original section of the administration building was built in 1892 and designed by architect Isaac G. Perry. It was tripled in size in 1906 and the addition included a slightly off-center 10-sided, 4+1⁄2-story castle-like tower.[2]
