Battery Lewis and Navesink Military Reservation

1402 Portland Road, Highlands , NJ 07732


Situated in Hartshorne Woods Park, Battery Lewis and the Navesink Military Reservation are among a number of different land and air-based military installations intended to defend New York Harbor and surrounding areas. During WWII, batteries for artillery were constructed on the site including Battery Lewis, a 600-foot casemated battery consisting of two 16-inch caliber gun emplacements connected by a corridor housing ammunition storage and power rooms. Still extant today, the concrete and earth encasements or bunkers protected personnel and equipment. During the Cold War era when strategic air power and nuclear weapons were on the rise, the site served as a missile defense and command center fitted with radar, computers, and electronic plotting devices. The Navesink Military Reservation is listed in the State and National Registers of Historic Places.

Visitors are welcome to tour Battery Lewis, the only 16-inch gun battery in New Jersey, view a WWII naval gun from the Battleship New Jersey, and explore 14 miles of extensive trails.
