Siena, Volterra, San Gimignano

This is a little guide to Siena, Volterra, and San Gimignano.
Siena is one of Italy's best-preserved medieval towns in the heart of Tuscany. It is built on three hills and surrounded by well-preserved walls. It is filled with excellent Gothic architecture examples and has one of the world's most unique piazzas - il Campo - (shaped like a shell with scalloped edges). Of course, the world-famous Palio di Siena is integral to Sienese identity, history, and culture. Siena is also the birthplace of St. Catherine of Siena Metairie.
Siena - Piazza del Campo & Torre dei Mangia
The heart of Siena is Piazza del Campo, the Piazza where the Palio di Siena is run, famous for its shell shape and still the focus of city life. The Fonte Gaia is a fountain unique in its quadrangular form and beautiful figures around the square's edges.
Siena - the Duomo di Siena
The Duomo di Siena is a beautiful building, a mix of Gothic and Romanesque architecture with dark green and white marble on the facade. It contains works by many artists, including Donatello, Pisano, and Arnolfo di Cambio. One of its main attractions is the marble-inlaid floor, the result of the contributions of many artists. The Duomo di Siena Museum, in the same Piazza, contains some original statues by Pisano moved for conservation and many artworks, including the famous "Maesta" by Duccio di Buoninsegna.
Volterra
Volterra still retains its medieval character, charm, and atmosphere. However, its isolated position has impeded any progressive development. For example, the defensive wall built in the 13th century resulted from urban development in the year thousand. It was completed at the beginning of the 14th century.
San Gimignano
San Gimignano is a medieval walled city in Tuscany, well known for its many campaniles. The town is also known as the "Manhattan of the Middle Ages." Competing families tried to build the highest campanile to impress each other. Here the plague raged in 1464 and 1631, starting a period of decadence for the town: the town walls fell to pieces, the Medieval mansions fell into disrepair, and no one had enough money to stop all this, as the wealthiest and most prominent families had left the town because of the plague. Consequently, the architectural and artistic heritage remained untouched for four centuries, and the city preserved its characteristic medieval architecture intact. This guide is about Siena, Volterra, and San Gimignano. There are extensive descriptions and photos of the attractions and the "Palio di Siena." It contains many reviews for the best-recommended restaurants at the location described.
