We visited another WW2-era structure in the Cape May area. This building is Fire Control Tower #23.
According to Cape May MAC:
Built in 1942, the tower was one of 15 towers that helped aim batteries of coastal artillery, stretching from North Wildwood, N.J. to Bethany Beach, Del. Four were in Cape May County, N.J.—the towers located in North Wildwood and Wildwood Crest were torn down and a third tower is located inside Cape May’s Grand Hotel, Beach and Philadelphia avenues. Fire Control Tower No. 23 is on land now part of the Cape May Point State Park.
Due to somewhat longer lines and unexpected crowding, we opted not to go inside the structure, but like most things back then… it was built to last… so maybe next time.
