Situated in the upper part of the town, the Cassero bridge house complex towers over the whole of the Valdichiana valley and still maintains its medieval defensive structure. The unmistakable bulk makes its the main reference point and symbol of Castiglion Fiorentino.

In the eighth century BCE, a village of huts occupied the entire hillside, which was later enclosed with a wall to defend the Etruscan acropolis. The present-day appearance of the bridge house is the product of conversions made from the eleventh century onwards, when the area became a castle to guard the more important roads, away from the wetlands.

In the Hellenistic period, the populated area also extended to Casseretto (the last defensive bulwark of medieval Castiglione), as indicated by the discovery of the Etruscan walls on the north side and the remains of an Hellenistic dwelling.

In the courtyard of the bridge house, the Tower stands regally: it was erected under fourteenth-century Perugian rule. The bell gable, which tops the tower and supports the “Campana Grossa” (large bell) appears to be more recent. On the southern side of the Casseretto, entrance to the inner courtyard opens up with a round arch, as the eighteenth-century staircase leads to the raised level of the tower. Today’s visitors can climb up to the top of the tower (about 35 metres) and enjoy views over the old town and the scenery of the Valdichiana and Val di Chio.
