The brick fortress on Park Avenue, the period rooms of the regiment, then the drill hall: fifty five thousand square feet under iron arches, the works standing in the dark like an installation.

The Seventh Regiment Armory on Park Avenue was built between 1877 and 1881 to designs by Charles W. Clinton, with interiors by Louis Comfort Tiffany, Stanford White and the Herter Brothers. Its drill hall spans 55,000 square feet under iron arches. A conservancy took over the building in 2007 and runs it as a venue for large scale art and performance.

The Gothic Revival brick armory with its crenellated towers, the Tiffany and Herter Brothers company rooms, the drill hall's wrought iron barrel trusses eighty feet high, the vast wooden floor, the balcony round the hall. Mood: an installation at dusk. Everything is procedural geometry with painted surfaces; nothing is a scan or a photograph. The room is an interpretation, and it hangs the New Yorkers the census recorded at this place first.
