Valle Peligna

The Valle Peligna, also known as Conca di Sulmona, is a plateau in central Abruzzo, southern Italy, included in the province of L'Aquila.

In prehistoric times, it was occupied by a lake which disappeared after a series of earthquakes approximately 300,000 years ago, leaving the land full of marshes but fertile.

[citation needed] The former barrier between the lake and the sea was in what are now the gorges of Popoli.

In addition to Sulmona, the main centers in the plateau include Raiano, Vittorito, Corfinio, Pratola Peligna and Pacentro.

[citation needed] Historically, it was inhabited by the Paeligni, an Oscan tribe.
