Theopetra Cave, located in the Meteora limestone rock formations of Thessaly, is likely to be the place of the oldest human construction on earth, as findings indicate that the cave was inhabited as early as 130,000 years ago.

According to archaeologists, evidence of human habitation in the cave can be traced without interruption from the Middle Palaeolithic to the end of the Neolithic period.Theopetra Cave is located at the foot of a 100-meter (330 foot) tall limestone cliff which looms over Theopetra village. The Lethaios River flows nearby.
Geologists say that the limestone hill was formed between 137 and 65 million years ago, during the Upper Cretaceous geological period.Archaeological evidence now indicates that humans occupied the cave during the Middle Palaeolithic period, approximately 130,000 years ago.
Theopetra was officially opened to the public in 2009, but closed a year later, as the remains of the stone wall were discovered during that year. It reopened a year later, but closed once again in 2016 due to the risk of landslides.
