I used to live near Sandy Hook in NJ. There was a Nike base there, but also several decades of various gun emplacements. They even secretly had nuclear warheads on the Nike Atlas missiles there to take out incoming bombers where the missiles were less accurate. No one in the towns around was told.

It’s an interesting historical place to walk around Fort Hancock as you see the batteries (no guns, sadly), and the Nike station.

The fortifications date from the civil war.

They have tours of the guns and missiles from time to time.
