The Labyrinth of Classical Mythology was a vast maze constructed by Daedalus on the island of Crete, in order to confine the Minotaur; the task was done at the command of King Minos. One theory suggests that the myth had some basis in the structure of the palace of King Minos at Knossos, in Crete, it being a multistoried royal palace with labyrinthine passages between rooms.
