The Dolmen of Menga is a megalithic burial mound called a tumulus, a long barrow form of dolmen, dating from 3750–3650 BCE approximately. It is near Antequera, Málaga, Spain.
It is one of the largest known ancient megalithic structures in Europe. It is 27.5 metres long, 6 metres wide and 3.5 metres high, and was built with thirty-two megaliths, the largest weighing about 180 tonnes.
After completion of the chamber and the path leading into the center, the stone structure was covered with soil and built up into the hill that can be seen today. When the grave was opened and examined in the 19th century, archaeologists found the skeletons of several hundred people inside.
