Museo Etrusco. Volterra (see pi 62). Vulci and Tarquinia These excavated sites, just over the Tuscany border in Lazio, have impressive Etruscan ruins, painted tombs and art collections. The Etruscan Canal at Ansedonia and purpose of the canal are debatable, but it may have been dug in Roman times to keep the harbour free of silt. Alternatively, it may have been part of a canal leading to the Lago di Burano, 5 km (3 miles) down the coast. This lagoon is 4 km (2.5 miles) long and has been turned into a wildlife refuge (rifugio faunistico) by the World Wide Fund for Nature. It is a very important habitat for wading birds.
