Knossos is a Bronze Age archaeological site on the island of Crete. It is at modern Heraklion. It may be Europe's oldest city.
Many Roman coins found on the site had 'Knosion' or 'Knos' on one side, and an image of a Minotaur or Labyrinth on the reverse. These are symbols from the myth of King Minos, supposed to have reigned at Knossos.
