Historically, Trasimeno was known as The Lake of Perugia and this name makes it easy to understand the importance that the lake has always had for the whole of north-western Umbria and for the Tuscan Chiana district. In prehistoric times, this lake was extended so as to almost reach Perugia.
All around the lake there are old small towns, and isolated castles, like Zocco castle, now in ruins, and a tower near Passignano. Monte del Lago was originally built to control the road from Trasimeno to Perugia.
