Tarquinia (Italian: [tarˈkwiːnja]), formerly Corneto, is an old city in the province of Viterbo, Lazio, Italy, known chiefly since it was (mis-)named after the ancient city of Tarquinii (Roman) or Tarch(u)na (Etruscan), although it was built across the valley on the opposite hill to that city, and overlies some of its widespread ancient cemeteries. Little is visible of the once great wealth and extent of the ancient city, but archaeology is increasingly revealing glimpses of past glories.
