Less well-known towns in Tuscany

From time to time, people ask about places to visit in Tuscany that are a bit less on the tourist radar than, say, Montepulciano or Greve. We found two on our recent trip. The first was Pietrasanta, which we visited from our base in Marina di Massa. (I'll be putting up a review of our hotel there, shortly.) It's located near Carrara, so no surprise, there's a big emphasis on sculpture. Outdoor, modern sculpture abounds throughout the town The piazza del Duomo is attractive, and the streets leading off it have some nice shops and restaurants.
Our second find was Massa Marittima. It has a very pretty duomo and other attractive buildings in the medieval, lower section. The upper "new" section (14th century) also has some noteworthy buildings, like the clock tower. We were utterly charmed by the director of the Antique Organ Museum, who personally guided us through, demonstrating several of the instruments and showing us his repair works in progress. We stayed at the Hotel Duca del Mare, which we found to be clean and reasonably priced, with nice rooms. The people who run it are extremely friendly and helpful.
