The dolmen Creu d’en Cobertella, east of the Torre del Sasstre, on the Costa Brava in Catalonia in Spain, was placed under protection and restored in 1964 and is the largest dolmen in Catalonia.
In the Middle Ages, it was known under the name Petra Coaperta or Petra Cooperta. Creu means cross in Catalan. The Serra de l’Albera has the largest concentration of megalithic monuments in Catalonia (110 dolmens, 19 menhirs, 7 stone boxes and a Neolithic settlement).
