10. Track Down NYC’s Former Military Buildings

Uncover the remnants of New York City’s former military establishments by finding former forts and armories. Untapped Cities has compiled list of the city’s former forts and armory buildings along with what they are used for today. Many forts and armories have been adapted for different uses like school buildings, apartments, shelters, and sport complexes, while others, like Castle Clinton, have been made into museum and memorials.

This June, you can also gain exclusive access into the abandoned Fort Totten and the Endicott Battery in Queens to preview a brand new art installation before it opens to the public, and learn about the former civil war fort that is now a public park.
