Piazza del Campo is the main square of the historic centre and is largely thought of as being one of the best and most beautiful medieval squares in the whole of Europe. Shaped like a large shell it is both visually and architecturally unique. The Palio horse race (link) is held twice a year around the Piazza del Campo.

Torre del Mangia is the bell tower of Palazzo Pubblico to which it is attached. The tower was built in the mid 14th century and at the time, due to it having been built to rival the one in Florence, it was the tallest structure in Italy.

Lining the sides of Piazza del Campo are many of the main historic buildings such as the Palazzo Pubblico, built at the end of the 13th century which was, and still is, the Town Hall.
Fonte Gaia is a monumental fountain which was first constructed in 1342 with underground pipes bringing water from 25 kilometres away. The current decorative surround to the fountain was constructed in 1419 by Jacopo della Quercia but the original marble panels were replaced by copies at the end of the 19th century.

The Basilica of San Domenico was built in the mid 13th century and is one of the most important religious buildings in the city. It was enlarged during the 14th century but suffered damage in the 15th century during a series of fires. This church houses several relics of St. Catherine of Siena.
Santa Maria dei Servi is a Romanesque style church built over the former church of St Clement in the 13th century. It underwent major reconstruction and refurbishment right up to the end of the 15th century. On the outside it is a simple church with a single doorway and a rose window but the interior, by contrast, is heavily decorated.
The bell tower was also built in the 13th century and was fully restored in the 20th century. San Francesco is a basilica church and was erected in the mid 13th century before being enlarged in both the 14th and 15th centuries. It was originally built in the Romanesque style but after the enlargements it was, and still is, Gothic.
It was badly destroyed by fire in 1655 and still looks rather stark inside.
