Monteriggioni 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, by assuming command of the Via Cassia running through the Val d'Elsa and Val Staggia to the west.

It borders on the communes of Casole d'Elsa, Castellina in Chianti, Castelnuovo Berardenga, Colle di Val d'Elsa, Poggibonsi, Siena and Sovicille.[4] The town is architecturally and culturally significant; it hosts several piazzas, and is referenced in Dante Alighieri's Divine Comedy.
