The dolmens of Valencia de Alcántara are distributed in various sectors of the municipality within private estates. In most cases they have accesses that can be visited or portholes to reach the megaliths. The funerary monuments are dated to a stage that runs between the Neolithic and the Chalcolithic or Bronze Age, about 5,000/6,000 years ago. In the construction typology there are dolmens with a single chamber or a chamber with a corridor in different states of conservation or restoration. The material used mainly for the large stone slabs (orthostats) is granite, and slate slabs also appear on various monuments.
