They are excavating Alepotrypa Cave, which is nearly four football fields long. The researchers compare the most striking room in the cave to a Cathedral.
Its a very awesome place, in the literal sense of the word, Parkinson said. I can only think that, several thousand years ago, when it was lit by torches, not by electric lamps like it is now, it would have been all that more striking.
They have unearthed tools and pottery that remain from a Neolithic (Stone Age) community between 5,000 and 8,000 years ago. Under the dripping stalactites, skeletons dating as far back as 8,000 years rest under layers of sediment.
Its the closest thing we have to something like a Neolithic Pompeii in the Mediterranean, Parkinson said.
