If you discover Siena in one day, start with the visit of Piazza del Campo.
Piazza del Campo is the heart of Siena, where you just must spend some of your time once in town. It’s a huge square and is also considered one of Europe’s greatest medieval squares. You can enjoy it while sipping a coffee in one of the several bars located there.
Impossible to miss the beautiful gothic building, the Duomo of Siena.
This Siena Cathedral was designed and constructed between 1215 and 1263 and is a popular tourist attraction.
