Antequera Town Hall Tourism Department. The Viera Dolmen is erected very few meters away from the Menga Dolmen, 5,000 to 4,500 years ago. They are quite similar regarding the morphology, construction and date, but the Viera one is quite smaller. It is a corridor sepulcher, where the passage and the burial chamber are clearly separated and divided by a square slab cut into the very same stone, in a similar way to the partition slabs of the Millares necropolis and the Gandul dolmens in Seville. The whole tomb is covered by a tumulus, like the Menga one.
