Ice Palace

The Ice Palace (氷の塔, Ice Tower) is the fifth dungeon of the Dark World in A Link to the Past.

It is located in the Southeast, in the middle of the large lake. Access to the dungeon is granted by swimming to the largest island in the Light World. Lifting up the black rock (which requires collection of the Titan's Mitt in Thieves' Town) reveals a portal; Link must step on it to be teleported outside Ice Palace entrance.

The main treasure is the Blue Mail, a tunic that increases link's physical defenses. The Ice Palace is possibly the first ice-themed dungeon in the Zelda series, followed six years later by the Ice Cavern from Ocarina of Time; it's also considered to be one of the most difficult in this game, although one of its rooms has its complexity "nerfed" in the GBA remake. The Palace's end boss is Kholdstare, a living formation of ice. After defeating the boss, Link receives a Heart Container and the 5th Crystal.
