One of the resources traditionally exploited in the region was honey collection. This spot, known as "El Colmenar de los Frailes," housed the Templar community's beehives. They were made from hollowed tree trunks, each with a stone slab placed on top as a lid, leaving small entrance areas for the bees. They lined the rocky outcrops of the Canyon.
