at Tajo Internacional
Archaeonomy is the branch of astronomy and archaeology which studies the sacred buildings or sites of the ancient civilisations with the aim of finding out about their astronomical knowledge. At Tajo Internacional, which is rich in prehistoric evidence, you will be able to connect with our ancestors under the stars. The dolmens of Valencia de Alcántara, with 41 constructions which have been declared Assets of Cultural Interest, stand out.
Moreover, the stars shine in a special way in places such as the ‘El Buraco’ Cave in Santiago de Alcántara and its slate dolmens; the ensemble of Cedillo, with the dolmen La Joaninha which was discovered in 1995; and the ensemble of Herrera de Alcántara.
Likewise, at least 50 slate dolmens are scattered over the municipal district of Alcántara. Here the Menhir del Cabezo stands out with its length of 4.65 metres; it is one of the few to survive in western Spain. Finally, on the Portuguese side it is well worth visiting the Megalithic Complex of Castelo de Vide and the Menhir de la Meada under a mantle of stars.
