Yup, that's Ft Hancock on Sandy Hook. It was originally a coastal artillery base covering the approaches to New York harbor. There was also a proving ground for testing artillery munitions. Later, it was a Nike Ajax missile site for the defense of New York City. It's now part of Gateway National Park. There is a LOT of history out there...

Oh yes... This is the lighthouse! (shot on 5X7 Ektachrome)
