They call it the treasury of atreus. i don't know the story. I think it's supposed to be a tomb. It's from the beginning of the maicenian civilization like 1,500 BC.
One thing I know for sure is that it's got some wicked awesome accoustics!!! OMG. The capstone to the opening is supposed to be 120 tons but it looked bigger than that. I say the aliens made it and you can quote me on that.
