ancient city had shrunk to a small fortified settlement on the "Castellina" location during the early Middle Ages, while the more strategically placed Corneto (possibly the "Corito" mentioned in Roman sources) grew progressively to become the major city of the lower Maremma sea coast, especially after the destruction of the port of Centumcellae (modern Civitavecchia). The last historic references to Tarquinii are from around 1250, and the last remains were destroyed in 1305. The importance of Tarquinii to archaeologists lies mainly in its necropolis, situated to the southeast of the medieval town, on the hill named "Monterozzi". The oldest tombs are , or shaft graves, containing the ashes of the dead in an urn. The oldest of them probably pre-Etruscan; in some of these tombs are hut-shaped urns, many of which contain well-preserved paintings of various periods; some show close kinship to archaic Greek art, while others are more recent, and one may belong to the middle of the 4th century BC. Sarcophagi from these tombs, some showing traces of painting, were preserved in the municipal museum, as were numerous Greek vases, bronzes and other objects. The name of Corneto was changed to Tarquinia in 1922. Reversion to historical place names (not always accurately), was a frequent phenomenon under the Fascist Government of Italy as part of the nationalist campaign to evoke past glories. Main sights Etruscan necropolis of Monterozzi The main necropolis of Tarchuna, part of which can be visited today, is the Monterozzi necropolis with some 6,000 tombs, at least 200 of which include beautiful wall paintings, and many of which were tumulus tombs with chambers carved in the rock below. The painted scenes are of a quality virtually unrivalled elsewhere in the Etruscan world and give a valuable insight into the secretive world of the Etruscans which is rarely documented. They show banquets with dances and music, sporting events, occasional erotic and mythical scenes. In the late period underworld demons escorting the dead on their journey to the beyond including scenes in the nether world were depicted, and also processions of magistrates and other symbols of the rank of the eminent members of the families buried there. Famous tombs include the Tomb of the Bulls, Tomb of the Augurs and the Tomb of the Leopards. During the second half of the 4th century sculpted and painted sarcophagi of nenfro, marble and alabaster came into use. They were
