Closer look at the Menga dolmen shows it was one of the greatest engineering feats of the Neolithic

A team of archaeologists, geologists and historians affiliated with several institutions in Spain has found that the Menga dolmen represents one of the greatest engineering feats of the Neolithic. In their study, published in Scientific Reports, the group used new technology to learn more about the stone that was used to create the ancient burial site and to explore how wood and rope would have been used in its construction.
