The Alepotrypa Cave is an archaeological site in the Mani region of the Peloponnese peninsula. In addition to being inhabited by early farmers, this site was used for burial and cult purposes. Archaeological evidence has revealed that this is one of the largest Neolithic burial sites ever found in Europe. Two adult human skeletons were found at the site from a burial dating to the 4th millennium BC, as well as remains from at least 170 separate persons. Archaeologists are uncertain about the significance of a Mycenaen ossuary, which has been dated to the 2nd millennium BC and appears to have been reburied at Alepotrypa. While there is no direct evidence, it is possible that the ossuary may link Alepotrypa to Tainaron, which was regarded as the entrance to Hades in classical mythology.
