Dolmenes (dolmens), more than 4,000 years old prehistoric tomb monuments, are Europe’s best preserved remains of the Bronze Age. Corridors, chambers and other rooms were made with large blocks of stone. Some rooms have a flat ceiling, others have a false dome. These were used for rituals, funerals and commemorations of ancestors. They are comparable to the Dolmens in the Netherlands, only the Dolmen of Antequera are much larger. They are the first form of monumental architecture in the prehistory of Europe and are still in perfect condition.
