Oldest Man-Made Structure Found in Greek Cave
The oldest known example of a man-made structure was found within a prehistoric cave in central Greece, according to the Greek culture ministry.
The structure is a stone wall that blocked two-thirds of the entrance to the Theopetra cave near Kalambaka on the north edge of the Thessalian plain. It was constructed 23,000 years ago, probably as a barrier to cold winds.
Excavated since 1987, the Theopetra cave is well known to palaeontologists as it was used and inhabited continuously from the Palaeolithic period onwards (50,000 to 5,000 years ago).
