Madison Avenue Facade of the Squadron A Armory
Also known as: Squadron A Armory

Why it's listed
Along the east side of Madison Avenue between 94th and 95th Streets in Manhattan, a long brick wall with corner towers is all that remains of the Squadron "A" Armory. Architect John R. Thomas completed the building in 1895, and the rest of it was razed in 1966. The surviving wall has eleven bays between two multistoried towers, crenelated parapets on brick corbels, round turrets, stone bartizans at second-floor windows, and a deeply recessed arched entry with a terra cotta barrel vault. It was listed as a picturesque example of 19th-century military architecture. The armory housed a cavalry unit that began in 1884 as a private riding group, joined the state militia in 1889, served in the Spanish American War, and was called into federal service in World War I. The wall was incorporated as the west edge of the playground of a new intermediate school designed by Morris Ketchum, Jr., & Associates to harmonize with the towers.
Significance in brief: The remaining section is described as a picturesque example of 19th-century military architecture, with monumental scale and a romantic, castle-like appearance. It also marks the history of Squadron A, a cavalry unit formed in 1884 that served in the Spanish American War and World War I. The wall was to be kept as the west edge of a new school playground.

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.
