Castle Hill MR
Completed in 1944 on the Crane Estate this two story station was built to look like a beach cottage from the sea. A pump house disguised as a garage was also built behind the station with a large tank inside. The side by side station was used for Fort Dearborn (Battery 103/Seamen) in Rye NH and Fort Ruckman (Battery 104/Murphy) in Nahant. An Anti Aircraft deck was located on the roof. for Portsmouth Harbor Defenses Command. After the Army left in 1948 the station was destroyed by Mrs. Crane in 1949. The entire property was transferred to the Trustees of Reservation in 1949 and they maintain the site today. There are no remains or known photographs of the station aside from a plan shown below. The pump house may remain but I am not sure yet.
