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.

Entrance to the Tower
It 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.

Themes and Navigation
The dungeon is larger in size than the first three encountered in the game. It has numerous floors, and features new enemies. Crystal Switches debut in this dungeon, the first appearance for these objects in the series. It's also the first time that Link encounters teleporters which take him into other parts of the dungeon. Finally, holes leading to lower floors also debut here, and their positions in the floor may change when certain special switches are pressed (this is the only way to get the main treasure of the dungeon, the Moon Pearl.) 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.

The Dark World counterpart of the Tower of Hera is Ganon's Tower.

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.

Trivia

 * The Tower of Flames from Four Swords Adventures has a very similar structure and design to the Tower of Hera. The boss of the Tower of Flames is three Dodongos, similar monsters to the Kodondos that appear in the Mountain Tower.
 * Footage of the Tower of Hera dungeon was used during the The Legend of Zelda 25th Anniversary Symphony during the Selected Shorts Suite when the Sanctuary Dungeon music is played.
 * The Tower of Hera is named after the famous ancient Greek Goddess, Hera. Hera was the wife of Zeus, the King of the Gods, and is rumored that she lived in a beautiful tower or palace, built on the top of Mount Olympus, the tallest mountain in Greece.
 * In Saudi Arabia, there is a cave of a similar name, the Cave of Hira, located on an important site in the Islamic culture. The cave is on the Mountain of Light outside the city of Mecca.
