Park Avenue Armory, as viewed from Lexington Avenue and 66th Street, 1937.

The Park Avenue Armory (also known as the Seventh Regiment Armory) is a massive 1880 Gothic Revival structure. The main entrance fronts Park Avenue between 66th and 67th Streets. (This photograph depicts the back end of the building on Lexington Avenue.)

Designed by Charles Clinton, the huge structure was the headquarters and administrative building for the 7th New York Militia Regiment. The most well-known feature (certainly in its current use as an arts space ) is the 55,000 square foot drill hall.

This regiment, from its beginnings, had a majority of members from the city's wealthy and elite families– it was known as the Silk Stocking Regiment. While all armories included additional rooms such as a reception hall, library, veterans room and staff offices, the interior of these rooms here were particularly spectacular and the work of some of the periods most well known designers and artists. Louis Comfort Tiffany designed (with a 24-year old Stanford White assisting) the Silver Room or "Trophy Room" and the Veterans Room, which is decked out in hand carved wood panelling, a coffered ceiling, and stained glass windows.

Today the building is still used by a detachment of the New York National Guard, Veterans of the 7th Regiment and the Park Avenue Armory Conservancy, a non-profit that programs unconventional performing and visual arts.
