Harbor Defense Museum

The Harbor Defense Museum, also known as The Caponier, is on the grounds of Brooklyn's Fort Hamilton. The museum is housed in a fort dating back to the 1800s. It is the only military museum in New York City. The museum is unique, as its one of just a few in the entire country that is funded and run by the Department of Defense.
