The Sacred Land (聖地, Holy Land) is a sub-world found in the Dark Realm within Adventure Mode in Super Smash Bros. Ultimate. It is located at the end of the west path. The boss of this sub-world is Ganon.
The Sacred Land is entirely based off of the triforce from The Legend of Zelda. Owl statues from The Legend of Zelda: Majora's Mask are scattered throughout and give players hints.
The Triforce of Courage section is based off of the Lost Woods in Ocarina of Time. In order to solve the section, the player must rely on the owl statues. While the player is in this section, Saria's Song / Middle Boss Battle plays.
The Triforce of Wisdom section is based off of Kakariko Village in Ocarina of Time and features torches forming a clock. The player must light the torches for a given time to unlock certain appearances. While the player is in this section, Dark World (For 3DS / Wii U) plays.
The Triforce of Power section is based on the Gerudo Desert and the Gerudo Fortress in Ocarina of Time. This land cannot be accessed until the player activates the Master Sword in the center of the land. The Gerudo Desert portion is made of two paths. The right path features easier spirit battles, but with more spirits in general. The left path features harder spirit battles, but with fewer battles. Both paths eventually merge in the Gerudo Fortress portion. While the player is in this section, Hyrule Castle (Outside) plays.
The Spirits found here are highly varied, though most relate to the Zelda series' themes of courage, wisdom, and power.
The boss of this sub-world is Ganon. In order to reveal his location, the player must defeat Young Link, Zelda, and Ganondorf. Sonic and Cloud must be defeated as well since they block the access to the Master Sword which reveals the Triforce of Power section.
While most of the fighters in this sub-world are accessed normally, Mii Brawler will only appear when the clock is set to 4:40.
