Portland Harbour was one of the primary embarkation ports for the US 5th Corps during the Normandy invasion.
The museum houses a fully restored, functioning Sherman tank that occasionally participates in public demonstrations.
The Admiralty Buildings were specifically chosen for the centre because they were the actual headquarters for the naval operations during the D-Day build-up.
Many of the artifacts on display were recovered from the local seabed near the harbour.
The centre features a 'mock-up' of a Higgins Boat, the landing craft used to transport troops to French beaches.
The site maintains a collection of original D-Day period uniforms and weaponry donated by veteran families.
Archaeological dives in the Portland area have contributed specific items to the collection that were lost during the chaotic loading phase in 1944.
The Castletown D-Day Centre is a living history museum situated on the Isle of Portland, specifically occupying the historic Admiralty Buildings. It commemorates the departure point for thousands of American GIs who embarked from Portland Harbour for the D-Day landings in June 1944. The site features an extensive collection of period military vehicles, including a restored Sherman tank and a 1944 Willys Jeep. Visitors can explore immersive displays that recreate the atmosphere of the embarkation points through authentic artifacts and interactive zones. The museum serves as a repository for local military heritage, highlighting the crucial role Portland played in Operation Overlord. Displays emphasize both the equipment used and the personal stories of the personnel stationed here. The facility is maintained to reflect the operational conditions of the era, offering a direct physical connection to the mobilization efforts of 1944.
