A Sanctum is the place to go to when affected by certain status effects. They are generally run by Great Healers, although these healers can often be found outside sanctums as well. Generally, Sanctums have large double-doors and a series of chairs with a path up the middle, leading up to an alter where the healer is found. They are very much similar to real-life churches, although the healers never mention religion in English, simply that they are "spreading goodwill". The Japanese text says they are spreading the word of 神, which could mean one god, multiple gods or even various spirits.
Sanctums provide the following services:
- Revive: this fully heals any downed Adepts in the party, which is the same effect as the Revive Psynergy and Water of Life.
- Cure Poison: this removes any poison or venom from one of the party's Adepts. This is the same as using an Antidote or the Cure Poison Psynergy.
- Repel Evil: This removes the Haunt effect from afflicted Adepts. This is one of the only ways to remove Haunt when not in battle.
- Remove Curse: This unequips any Cursed items from Adepts, and is the only way of removing them. It does not remove the Curse from the item, so re-equipping it will require another does of "Remove Curse" to get rid of. The only way to safely use cursed equipment is to equip the Adept with the Cleric's Ring.
All Sanctums require a "donation" for their services. The amount is based on the character's level.

- By holding down L and Start while loading the game, the player will resume in the sanctum of the last town visited, rather than the exact point that they had saved at. This is not possible in Golden Sun: Dark Dawn. In all games, however, the player will return to the last visited Sanctum if they are defeated in battle; in Dark Dawn, the statues of The Wise One also work for this purpose.
- While it is never stated what kind of religion the sanctums follow, one does seem to exist given that healers in Dark Dawn will tell the player that "the gods will always protect [them]". There are some Christian undertones, however, such as the priest in Champa who describes the people there as "[his] flock".
- While not explicit for other temples, the Japanese script makes clear Sol Sanctum and Vale worship The Wise One.
