Trasimène
Trasimène  was a department of the First French Empire from 1809 to 1814  in present-day Italy. It was named after Lake Trasimeno. It was formed on 15 July 1809, when the Papal States were annexed by France. Its capital was Spoleto. The department was disbanded after the defeat of Napoleon in 1814.
