Dolmen de la Chabola de la Hechicera Monument · Elvillar/Bilar, Cuadrilla de Laguardia-Rioja Alavesa, Álava Passage dolmen discovered in 1935, with a chamber made of nine slabs and a gallery of six more, with remains from the late Neolithic (some 5,000 years ago), the Bronze Age, and Roman times. Local tradition says that on the morning of Saint John's feast, the singing of a sorceress could be heard there though no one ever saw her, and that anyone who approached to look would be turned to stone. 1935 Photo: Josu Goñi Etxabe (Public domain) What to see and do in Elvillar/Bilar
