Description: Abandoned concrete gun platforms, formerly part of the Proof Battery of the Sandy Hook Proving Ground, in use from 1901-1919. Soldiers used a 20-foot gantry crane on rails to lift guns and carriages onto the platforms to be tested, or "proved". Sandy Hook is now part of the Gateway National Recreation Area; these platforms are near North Beach.
