Clermont Avenue, east side, between Myrtle and Willoughby Avenues, viewing south from the former and showing the 52nd Field Artillery Armory, also known as the 105th Regiment Field Armory, 1925.

Built in 1873, the William Mundell-designed Clermont Armory was, at the time, the largest hall without pillars or obstructions in the United States. Mundell’s ornate Second Empire facade was rebuilt in comparatively bland "Neo-Medieval" style in 1911, the 23rd regiment having relocated to a new and larger armory at Bedford and Atlantic Avenues in 1895.

When the National Guard left in 1964, the Clermont Armory became a storage facility for the Department of Sanitation, falling out of use after 1989. The building has since been redeveloped for residential use.
