An ancient Islamic necropolis containing over 4,500 bodies has been uncovered in northeastern Spain, with archaeologists excavating more than 400 tombs in the five-acre site. The tombs were discovered in an 8th-century burial ground in the town of Tauste, near Zaragoza in Aragon, Eva Gimenez, an archaeologist currently excavating the area with the Paleoymás archaeology firm, told CNN.

Muslim occupation of Tauste had been considered "incidental and even non-existent" by traditional and written sources, researchers from the University of the Basque Country have said -- but the region's cultural association had long suspected the area had been home to a large Islamic settlement because of architectural clues and human remains found in the town, Miriam Pina Pardos, director of the Anthropological Observatory of the Islamic Necropolis of Tauste with the El Patiaz cultural association, told CNN.
