The Door That Does Not Open

The Door That Does Not Open is a location from Zelda II: The Adventure of Link. It is located within the North Castle and leads to the room where Princess Zelda sleeps. The only people who know how to open the door are the descendants of the Impa family who served the King. Prior to the game's events Impa opens the door by touching it with Link's left hand which bared the Crest of Hyrule. Inside Link sees Princess Zelda and learns of how she was put into a deep sleep by an Evil Wizard.
