The Landing Ship, Tank (LST) Building, determined eligible for listing in the National Register of Historic Places in 1998, is a unique structure and an example of early joint forces' operations. The Army, Navy, and British Admiralty contributed to its design, construction, and use. Design modifications of LST ships, used to transport tens of thousands of troops in W.W.II, resulted from experiments conducted in the building. After those experiments were completed, the building provided training for troops in tank embarkation and debarkation techniques. Since the 1970's, it has been used to store antique tanks. The building replicates every detail of an LST ship's tank deck, including interior girders and rivets. Details of the upper deck, such as railing and pilot house, were also replicated. Originally, the building was not equipped with windows because the tank deck of an LST ship rides below water level, and windows were later added when it was converted to a classroom.
