Tower of Hera (A Link to the Past)

The Tower of Hera, also known as the Mountain Tower, is the penultimate dungeon in the Light World in A Link to the Past, and the last of the three "Sanctuary" dungeons that contain the Pendants of Virtue. The Dark World equivalent to this tower is Ganon's Tower, which is also the penultimate location in that world.

Entrance to the Tower
The Tower is located at the top of Death Mountain. In order to climb Death Mountain, and thus gain access to the Tower, Link must use the Power Glove previously obtained from the Desert Palace. Link must also make a brief trip into Dark World and escape using the Magic Mirror he obtained from the Lost Old Man in order to get to the other side of Spectacle Rock, where the tower is located.

Themes and Navigation
The dungeon has many more floors than the previous dungeons encountered in the game, and features a number of new enemies, the most prominent of which are the Hardhat Beetles, strong enemies that are most effectively defeated by knocking down the many pitfalls found throughout the journey to the top of the tower. These pitfalls make their debut in the series here, allowing Link to drop from one floor to a lower one without taking damage, but losing progress instead. Their positions will change when certain star-shaped switches are walked on, and utilizing these pits and their changing locations is the only way to obtain the elusive Moon Pearl. Unlike the previous two dungeons, the treasure in the Big Chest is not vital to the completion of the dungeon. Crystal Switches debut in this dungeon, the first appearance for these objects in the series, and the raising and lowering of the orange and blue blocks in conjunction with the placement of the pits is key to progressing through the tower, and accessing jars in the room prior to the boss. The boss is Moldorm, which is fought atop a perch surrounded by holes. Should Link fall into a hole, he will find himself on the previous floor, and he will have to begin the battle again. After defeating this boss, Link receives a Heart Container and the Pendant of Wisdom.

A Link to the Past comic
In the A Link to the Past comic, Link finds himself in front of the Tower of Hera after waking up from a dream he shared with Princess Zelda. Link enters the Tower of Hera and climbs to the top to battle a Moldorm, who this time has an appearance of a giant spider. After Sahasrahla informs Link that the Pendant of Wisdom is in the creature's eyes, Link seizes the pendant by pulling it out with his arm. Upon grabbing the pendant, his arm, previously wounded is instantly healed, and the young hero uses the spider to ride down the tower, defeating Moldorm.
