The cemetery was established in Nettuno, as a temporary battlefield cemetery on 24 January 1944, two days after Operation Shingle began, the Allied landings at Anzio and Nettuno on mainland Italy. The majority of burials at the cemetery are of men that died fighting in the liberation of Sicily, code-named Operation Husky ; in the landings at the Salerno, code-named Operation Avalanche and the heavy fighting northward; and the landings, code-named Operation Shingle, at Anzio and Nettuno and expansion of the beachhead ; and in air and naval support in the regions.
Layout
The cemetery covers with a gentle slope rising from a pool with an island and cenotaph flanked by groups of Italian cypress trees. Beyond the pool is the immense field of headstones of 7,861 of American military war dead, arranged in gentle arcs on broad green lawns beneath rows of pine trees. A wide central mall leads to the memorial, rich in works of art and architecture, expressing America's and Italy's remembrance of the dead. It consists of a chapel to the south, a peristyle, and a map room to the north. On the white marble walls of the chapel are engraved the names of 3,095 of the missing. Rosettes mark the names of those since recovered and identified. The map room contains a bronze relief map and four fresco maps depicting the military operations in Sicily and Italy. At each end of the memorial are ornamental Italian gardens. There is a wall of remembrance commemorating 3.095 missing in action service personnel. In May 2014, a visitors' center was opened. The center displays photographs, films, and displays of the Allied advance in Sicily and Italy as well as personal stories of those involved.
visited the cemetery on All Soul's Day, Thursday, 2 November 2017, in a brief papal visit to the area for the commemoration, where he toured the cemetery grounds and placed flowers on some grave headstones, including an unknown soldier, and Italian-American soldier, and a Jewish soldier. Afterwards, in purple, as is custom for the day, he celebrated Mass and preached a homily at the cemetery. Following the visit there, he moved on to the site of the Ardeatine massacre, named for the forested area in which it took place.
