Castiglione del Lago is a town in the Province of Perugia of Umbria (central Italy), on the southwest corner ofLake Trasimeno. Orvieto is 59 km (37 mi) south, Chiusi is 21 km (13 mi) to the south west, Arezzo is 56 km (35 mi) to the north west, Cortona is 21 km (13 mi) to the north and Perugia is 47 km (29 mi) to the south east.

Castiglione del Lago has evolved on what used to be an island - the fourth island of Lake Trasimeno, in its south west region. Over the centuries, as the town grew, the flat gap between the island and the shore was filled with piazze, houses, churches and other buildings.

The newest parts of the city are at some distance from the old, so the centro storico (historical center) of Castiglione del Lago is a well-preserved medieval locality that seems to be governed by a "law of threes". In the town walls there are three gates, and inside the town there are three piazze and three churches.
