UPDATE: The author has not yet visited this museum near Cassino, but received this information and the photos from the directors:
The panels in the museum at Castelforte describe (in English and Italian) the phases of battle along the Garigliano front. Exhibited are the uniforms, weapons, documents, and equipment of the armies involved, which included Italian, British, American, French, and German forces. In each section a monitor shows films related to the narrative.
HOURS: The museum is open by appointment. Please email the director at: LineaGustavFronteGarigliano@gmail.com
