The set of dolmens in the Valencina de la Concepcion district of Seville can be found on a hill in Aljarafe. The dolmens date from 2000 B.C., that is, the Eneolithic or Chalcolithic period, the transition period between the Stone Age and the Bronze Age. This is therefore a set of dolmens that date from a relatively late prehistoric period. There are about 20 dolmens in this area. You can visit one called La Pastora with a 46m-long passage and a shorter one known as Matarrubilla. To round off your visit to the monument, you can watch a short film in the Casa de Cultura in Valencina de la Concepcion where you can also see an exhibition of the objects found during excavation work. Visits must be arranged by telephone.
