Cave of Pedra Furada

The Cave of Pedra Furada is a small cave located in the municipality of Vila Franca de Xira, approximately 20 km north of Lisbon, Portugal [1]. The cave was formed through karstification of the limestone Upper Jurassic Massif [1]. Archaeological excavations have revealed evidence of intermittent human occupation during at least three distinct periods between the end of the fourth millennium BC and the second millennium BC [1]. This evidence indicates prolonged or repeated use of the site throughout prehistoric times, making it a significant archaeological location for understanding Neolithic and Chalcolithic human activity in the region [1].
