Much of the medieval center has been well preserved and restored. The Duomo (beautiful 'deposition of Christ'), Baptistery and Piazza dei Priori are required viewing. If you are interested in Etruscan art and culture, the Museo Etrusco Guarnacci contains thousands of finds excavated from nearby tombs and burial sites. Some of the jewellry is breathtakingly beautiful and intricate. The Pinacoteca and Museo Civico shows mostly religious art from 14th and 15th century AD. There are English explanations. The adjacent alabaster museum is disappointing: no guiding theme, explanations in Italian only, lackadaisical presentation.
Alabaster shops and workshops are all over the place and sell mostly tourist trinkets. Beautiful pieces start at EUR 1000 or above and require shipping (VAT deducted for export). Many restaurants, pasticcerie, snackbars if all the walking around town makes you hungry and thirsty.
