Cave of Pego do Diabo

The Cave of Pego do Diabo (also known as Loca do Gato or Cat's Den) is a small karst cave in a Turonian limestone outcrop located about 250 metres above sea level in the municipality of Loures, about 20 km north of Lisbon in Portugal. The erosion of the outcrop resulted in a set of openings in the rocks wide enough to be exploited by humans. Several archaeological studies have been conducted within the cave, which give insights into the duration of Neanderthal presence on the Iberian Peninsula and to the presence of carnivorous animals during the Paleolithic.
