The name of Tarquin rings a bell with many who learned off by heart at school of how
'Lars Porsena of Clusium, by the nine Gods he swore
The royal house of Tarquin should suffer wrong no more.'
However the city itself, or rather the old part of the city, will have medieval rather than Etruscan sights for you. The National museum itself, full of Etruscan pottery, metal artefacts and paintings, is housed in a palace of the later Middle Ages. The Palazzo Communale is a rare lay medieval building and there are a number of Romanesque and Gothic churches.
If you want to see something Etruscan outside the museum, take a bus [easier than the guide books make it sound] to the necropolis and go down at least some of the flights of steep steps to see the wonderful painted tombs. It's well worth the €4 charge to hire an audio guide for your visit. [edit text][editors]
