Before the Greeks, there were the Minoans. The Palace of Knossos is one of the largest and most restored Minoan palaces on Crete. Built around 1700 BC, these ruins are the oldest we've ever visited, but this site was actually inhabited even earlier back in 7000 to 3000 BC. With great age comes a few great myths, and this place is rumored to be the labyrinthine palace of King Minos and the Minotaur and also where Icarus lost his wings.
