Tarquinia (Italian: [tarˈkwiːnja]), formerly Corneto, is an old city in the province of Viterbo, Lazio, Italy known chiefly for its ancient Etruscan tombs in the widespread necropoleis or cemeteries which it overlies, for which it was awarded UNESCO World Heritage status. In 1922 it was renamed after the ancient city of Tarquinii (Roman) or Tarch(u)na (Etruscan). Although little is visible of the once great wealth and extent of the ancient city, archaeology is increasingly revealing glimpses of past glories.

A quiet provincial town 35km northwest of Rome, Cerveteri is home to one of Italy's great Etruscan treasures – the Necropoli di Banditaccia. This ancient burial complex, now a Unesco World Heritage Site, is all that remains of the formidable Etruscan city that once stood here.

Necropolis of Tarquinia, called also Etruscan necropolis of Monterozzi, overlies on a highland to the east of the city with some 6000 tombs, many of which were covered by tumulus with chambers carved in the rock below. The oldest ones date from VII century BC. Among thousands graves, at least 200 are decorated with a number of frescos which are the main core of the Etruscan art came to us so far and the largest evidence of ancient painting before Roman age. Together with the necropolis of Cerveteri it is one of the most important archaeological sites of the Etruscan civilization.
