Valle Peligna

The Valle Peligna, also known as Conca di Sulmona, is a plateau in central Abruzzo, southern Italy.

The valley takes its name from the Greek term peline, meaning "muddy": this refers to prehistorical times, when it was occupied by a lake which disappeared after a series of earthquakes (the former diaphragm with the sea was in what are now the gorges of Popoli), leaving the land full of marshes but fertile. Three hills near Sulmona are the relics of the single island in the lake.

It is crossed by the rivers Aterno and Sagittario, and is bordered by the Fucino basin by east. Apart Sulmona, the main centers in the plateau include Raiano, Vittorito, Corfinio, Pratola Peligna and Pacentro.
