The Royal Crypt is a mini-dungeon from The Legend of Zelda: The Minish Cap. The entrance to the Royal Crypt can be opened only if Link uses the power of the White Sword to activate the three switches in front of the northern-most gravestone in the Royal Valley. The mini-dungeon is short, but contains many enemies and traps that Link must overcome.

Inside, Link meets the ghost of the former King of Hyrule, King Gustaf, who gives him a golden Kinstone Piece, which he needs to open the door to Veil Falls.

Interestingly, the music in the Royal Crypt is a remixed version of that played in dungeons in The Legend of Zelda.
