Ganon's Tower
From Zelda Legends Wiki
The tower, built by Ganon, out of which he runs his evil schemes. There have been at least three of these towers: in ALttP, on top of the mountain in the Dark World; in OoT, in place of Hyrule Castle (destroyed when Link defeated Ganondorf); and in TWW, on top of the mountain next to Hyrule Castle.
