Knossus Palace: perhaps the Cretan Labyrinth where Theseus killed the Minotaur.

Theseus is an archaic hero who protects society from monsters and helps to define its values. In Kinsmen he kills the murderous Creon and decides the fates and marriages of his captive Kinsmen. He does something similar in defeating the Amazons and regulating marriage in the Athens of Midsummer Night's Dream: by the end of the play the Athenian law has been modified in practice to let Hermia marry the man of her choice not her father's. As for the myths about this palace, in Henry VI, Part 1, Shakespeare has Suffolk brooding over how his affection for King Henry VI's bride, Margaret, might get him into trouble:

SUFFOLK. O, wert thou for myself! But, Suffolk, stay;
Thou mayst not wander in that labyrinth;
There Minotaurs and ugly treasons lurk.
Solicit Henry with her wondrous praise. (V.iii.187-90)
