The province of Perugia was created in 1860 as Province of the Umbria. At that time, the province was larger than now because the present Province of Terni was included.
In 1927, the old province of the Umbria was divided in two provinces, Perugia and Terni.
The main river in the region is the Tiber. The largest lake of the province, and of Umbria, is the Trasimeno, one of the largest lake of Italy.
The highest mountain in the province is Cima del Redentore, in the same group of mountains of the Monte Vettore, with an altitude of 2,448 m (8,031 ft).[3]
There are four regional natural parks in the province of Perugia: Parco di Colfiorito, Parco del Lago Trasimeno, Parco del Monte Cucco and Parco del Monte Subasio. The Monti Sibillini National Park (Italian: Parco Nazionale dei Monti Sibillini) is mainly in the Manche region but part of it is in Umbria.
The largest comune is Gubbio, with 525.78 km2 (203 sq mi) and the smallest is Paciano, with 16.91 km2 (7 sq mi).[5] The comune with fewest inhabitants is Poggiodomo with 117 inhabitants.
