Clusium
Clusium was an ancient city in Italy, one of several found at the site. The current municipality of Chiusi ( Tuscany) partly overlaps this Roman walled city. The Roman city remodeled an earlier Etruscan city, (Clevsin in Etruscan; in Greek Κλύσιον Klúsion or Κλούσιον Kloúsion; Umbrian'' 'Camars'''; Latin Clusium), found in the territory of a prehistoric culture, possibly also Etruscan or proto-Etruscan. The site is located in northern central Italy on the west side of the Apennines.
