The Fucine Lake was a large endorheic karst lake between 650 and 680 m above sea level and surrounded by the Monte Sirente-Monte Velino mountain ranges to the north-northeast, Mount Salviano to the west, Vallelonga to the south, and the Valle del Giovenco to the east-southeast. Located in western Abruzzo in central Italy, the town of Avezzano lies to the northwest, Ortucchio to the southeast, and Trasacco to the southwest of the historic lake. Once the third largest lake in Italy after Lake Garda and Lake Maggiore, it was finally drained in 1878.
