Trasimene Lake,

Trasimene Lake, a shallow Italian lake lying between the towns of Cortona and Perugia. Surrounded on all sides by hills, it is about 10 miles in length by 8 in breadth. There is no outlet, and the flat and reedy margins are of late planted with eucalyptus trees. In 1896 a canal was begun to regulate and partially drain the lake, which is memorable for the great victory obtained by Hannibal (q.v.) in 217 B.C. over the Romans.
