On the road that goes to Florence from Siena, you reach Monteriggioni with the well-preserved thirteenth-century boundaries and the 14 towers that encircle the village forming an impregnable fortress.
Continuing to north-east you find San Gimignano, picturesque town on the hills of Valdelsa, ancient etruscan settlement, famous for the forest of perfectly-preserved imponent medieval towers.
The most important monuments are Piazza della Cisterna, the Palazzo del Podestà, the Cathedral, the Palazzo del Popolo – that entertains with the Town hall the Museums and the Pinacoteca Civica – and the Romanic-Gothic church of Sant’Agostino.
Less then 15 minutes of auto to the west there is Volterra, medieval city where can be admired the conspicuous rests of the vast etruscan boundaries and one of the most suggestive italian square, Piazza dei Priori, where it dominates the Prior Building, the Romanic Cathedral and the Quadrivia dei Buon Parenti, knot of the medieval city.
Not to lose the Etruscan Arch and the “Guarnacci” Etruscan Museum
