This five-story concrete tower with attached barracks was completed in September 1943 on a leased 0.23 acre site as a Base-End Station (with DPF) for Battery 103/Seaman (B14 S14) at Fort Dearborn. The roof deck was used for the anti-aircraft intelligence service (AAIS OP 13). Before the tower was actually built, this site was planned as a double station to also serve Battery 101 at Fort Williams, Cape Elizabeth, Maine. Battery 101 was never built, so this station served only Portsmouth, and the design of the tower was slightly altered to remove one floor from the top. This tower was almost identical in design to the tower at Halibut Point in Rockport, Massachusetts. The tower and barracks were demolished by the land owners in either 1949 or 1950. There are no visible remains.
Located on Great Hill Road at Gelaspus Point (Great Hill), Kennebunk Beach, Maine.
