Dolmen of Alberite Monument · Villamartín, Sierra de Cádiz, Cádiz The Alberite dolmen is located in the municipality of Villamartín (Cádiz), within the megalithic necropolis of Alberite I. It was discovered in 1993 following a Civil Guard investigation after a looted funerary assemblage was recovered, and it is one of the oldest dolmens on the Iberian Peninsula, some 6,000 years old. Its excavation, led by Francisco Giles Pacheco and José Ramos Muñoz, brought to light a gallery some 23 metres long with a monumental entrance flanked by two large orthostats, some with schematic ochre paintings and engravings of weapons, moons and suns. Inside, the remains of two individuals were found with their bones dusted with ochre, along with an assemblage of polished stone, necklace beads, amber and a large quartz crystal.
