Monteriggioni is a comune in the province of Siena in the Italian region of Tuscany. It is a medieval walled town, located on a natural hillock, built by the Sienese in 1214–19 as a front line in their wars against Florence.

The roughly circular walls, totalling a length of about 570 metres (1,870 ft) and following the natural contours of the hill, were built between 1213 and 1219. There are 14 towers on square bases set at equidistance, and two portals or gates.

Monteriggioni is so well-preserved that it’s worth traveling to see it. There are only about 50 full-time residents, and even though the town has its share of tourist shops, you can still imagine what life was like here in the Middle Ages.
