Hyrule Castle is where Princess Zelda and the other Royal Family members reside, and is situated inside Hyrule Castle Town. Not much of the castle is seen in the game, as Link has to sneak by the guards in the gardens in his first encounter with the castle. He meets up with Princess Zelda in the central courtyard.
After Link draws the Master Sword and is sealed within the Sacred Realm for seven years, Hyrule Castle is attacked by Ganondorf. It is destroyed and Ganon's Tower is built on top of its location.
