The Astral Observatory is a recurring location in The Legend of Zelda series.[1]

Features and Overview

Majora's Mask

The Astral Observatory a small building outside the walls of Clock Town in Termina Field in Majora's Mask. It is home to a giant telescope, which is able to view the entire landscape of Termina, and also serves as the hideout of the Bombers.[2] Although the Observatory is located in Termina Field, the building is entirely fenced in, preventing entry through normal means outside. The primary way to get there is through a hidden passage in East Clock Town.

The passage to the Observatory is guarded by one of the 6 children of the Bombers, who must be told a 5-digit password in order for Link to gain entry. The password is acquired by popping the balloon in North Clock Town, talking to Jim, finding every member of the Bombers hidden throughout town, and proceeding to tell the password to the Bomber guarding the passageway. Once Link regains his Hylian form and returns to the First Day, he can play the game again to reenter the underground tunnels.

Once Link enters the tunnels, he must go through a small sewer, defeat a Skulltula, destroy another balloon, then go up the ladder leading to the observatory itself.

Link can also use a Deku Flower in Termina Field to enter the Observatory, although curiously it is not present during the Retrieval of the Ocarina of Time.

At the entrance, Link can meet the famous dancing Scarecrow, Pierre. Upstairs, the hero will find the astronomer named Professor Shikashi with the huge telescope overlooking Termina Field.[3] There is a Moon's Tear encased in a glass next to the telescope, and upon checking it, Professor Shikashi comments on how he finds the stones falling from the Moon's eyes, and how they have been falling recently.[4] By using the telescope to gaze at the Moon, Link can obtain his own Moon's Tear, which is required to start the Deku Flower Trading Quest. Through the telescope, Link can also see two men waving at him, signifying the presence of holes in the ground that he can venture into. The Part-Timer can also be seen in a Tree, trying to grab 40 Rupees.

Breath of the Wild

The Astral Observatory is the chamber in which Calamity Ganon is fought in Breath of the Wild. It is a hollow, hemispherical chamber made from ancient Sheikah technology situated far beneath the Sanctum. Scattered on the floor along the walls of the Astral Observatory are various items which can assist Link in the fight against Calamity Ganon.

Following Calamity Ganon's escape from Zelda's sealing magic, Link and Calamity Ganon both safely fall into the Astral Observatory and engage in combat. If Link has freed Divine Beasts from Calamity Ganon's control, the Champions piloting each Divine Beast—in the same pattern of the aforementioned beasts that Link would otherwise fight[5][6][7][8]—will launch an attack on Hyrule Castle and converge the beams emitted from their Divine Beasts down the pit, pelting Calamity Ganon with an array of lasers which whittle his health down cumulatively. The damage dealt from each Divine Beast is measured in increments of 12.5%, with all four Divine Beasts inflicting enough damage to remove 50% of Calamity Ganon's total health. If Link has not freed any Divine Beasts, the battle will begin with no initial damage dealt to the Scourge of Hyrule Castle. Upon defeating Calamity Ganon, he will shed his mortal form and escape from the Astral Observatory to Hyrule Field. Following suit, Princess Zelda will transport Link to Ganon's location, where she explains that he has assumed his most true and basic form as the very embodiment of his rage, Dark Beast Ganon, in a final attempt to destroy Hyrule.[9]



  • In Majora's Mask, the two men that wave at Link through the telescope closely resemble the man within the Oceanside Spider House, and the sons of the Cursed Rich Man from Ocarina of Time. It is likely that they are the Terminan counterparts of the latter, although any relationship to the former is unknown.
  • On the First and Second Days in Majora's Mask, the Skull Kid will taunt Link and fly away if he looks at him through the telescope. However, on the Final Day, the Skull Kid will simply direct his gaze towards the encroaching Moon.
