The Anzio Landing Museum was inaugurated on January 22, 1994, on the 50th anniversary of the landing, at the initiative of the "Centro di Ricerca e Documentazione dello Sbarco e della Battaglia di Anzio – ODV" association.It is housed in one of the rooms of the historic 17th-century Villa Adele, located a short distance from the train station and the city center. The museum is divided into four sections dedicated to the main forces that faced each other at Anzio: the American, British, German, and Italian sections. Each section houses uniforms, weapons, decorations, documents, battle plans, photographs of veterans, and everyday objects, all rigorously authentic.
The Museum also has a photo library, a tape library, a library, and a newspaper library. The collection is further enriched by flags, period prints, motorcycles, and other artifacts, with ongoing expansion made possible by donations from other museums, veterans' associations, and private citizens of the nations involved in the conflict.
Numerous artifacts come from the seabed near Anzio, where aircraft, landing craft, warships, and cargo ships, often sunk with many of their crews, still lie at various depths. Among these, the British destroyer Janus (sunk with 158 men), the cruiser Spartan (with 46 dead and 42 wounded), and the hospital ship St. David (sunk with 57 men and two nurses, despite being prominently marked with the Red Cross and protected by the Geneva Convention) are particularly noteworthy.
