Siena is located in the central part of Tuscany, in the middle of a vast hilly landscape between the Arbia river valley (south), the Merse valley (south-west), the Elsa valley (north), the Chianti hills (north-east), the Montagnola Senese (west) and the Crete Senesi (south-east). The city lies at 322 m above sea level.

 

The Siena Cathedral (Duomo), begun in the 12th century, is a masterpiece of Italian Romanesque-Gothic architecture. Its main façade was completed in 1380. The original plan called for an ambitiously massive basilica, the largest then in the world, with, as was customary, an east-west nave. However, the scarcity of funds, in part due to war and plague, truncated the project, and the Sienese created a subdued version from the original plan's north-south transept. The east wall of the abandoned original folly of a nave still stands; through an internal staircase, visitors can climb for a grand view of the city. 

The Basilica of San Domenico, also known as Basilica Cateriniana. The church was begun in 1226-1265, but was enlarged in the 14th century resulting in the Gothic appearance it has now. However, aspects of the Gothic structure were subsequently destroyed by fires in 1443, 1456 and 1531, and further damage later resulted from military occupation (1548-1552). It is a large edifice built, like many contemporary edifices of the mendicant orders, in bricks, with a lofty bell tower on the left (this was reduced in height after an earthquake in 1798). The church contains several relics of St. Catherine of Siena.

 

The Torre del Mangia is a tower in Siena. Built in 1338-1348, it is located in the Piazza del Campo, Siena's premier square, adjacent to the Palazzo Pubblico (Town Hall). When built it was one of the tallest secular towers in medieval Italy at 102 meters.
