Lago Trasimeno

Lake Trasimeno, also referred to as Trasimene or Thrasimene in English, is the largest lake on the Italian peninsula south of the Po River with a surface area of 128 km2, slightly less than Lake Como. No major river flows directly into or out of Lake Trasimeno and the water level fluctuates significantly according to rainfall levels and the seasonal demands from the towns, villages and farms near the shore.
There are castles all around Trasimeno, many in the center of small towns while others are isolated and in ruins. Castiglione del Lago, Passignano, Magione, Maggiore, and Polvese islands all have castles, while Zocco Castle, Montali Castle, and others are on hilltops.
The Guglielmi Castle in Maggiore Isle was built in the late 19th century on the foundation of an old Franciscan church, and for many years was a popular place in the Trasimeno area.
Between Monte del Lago and S.Feliciano is Zocco castle, ruined for decades.
The Vernazzano leaning tower, around 20 metres in height, leans like the famous leaning tower of Pisa.
