Province of L'Aquila, Abruzzo, Italy
Besides the natural lakes of Scanno and Barrea, there is the large artificial lake of Campotosto. In the Gran Sasso mountain there is also the southernmost glacier in Europe, called the Calderone, which is unfortunately shrinking year after year.
The province has a very low population density, and a territory full of castles and fortified medieval boroughs on top of mountains. It included once the largest lake in the Italian peninsula, Lake Fucino, where in antiquity the Romans came on holiday, which was drained with the third biggest engineering project in the late 19th century (the other 2 being the Eiffel Tower and the Suez Canal). The Fucino land is today a flourishing agricultural area, and an important technological district in the region.
