As its name would suggest, the entire village is symmetrical, and each inhabitant of the village has their own twin. In the village lies the entrance to Skull Dungeon, home to the fourth Essence of Time. Inside the Middle House, which serves as the town hall for the village, lies the Tuni Nut, the village's sacred symbol that holds the village in balance. In the present age, the Middle House is replaced by a Gale Tree, where Link can gather his first Gale Seeds. The tree also provides easy warp access to the village, which can otherwise only be reached by a bridge spanning the Nuun Highlands in the present.
In search of the fourth Essence of Time, Link travels to the Nuun Highlands where a bridge crosses over to the Talus Peaks where the village is found. However, the bridge will not be built upon Link's arrival. At the request of Mutoh, the head carpenter, Link gathers up all the workers on break, with the help of his animal companion (either Ricky, Moosh, or Dimitri, depending on certain choices Link has made on his adventures). The workers will then build the bridge, allowing Link to enter the village.
When Link arrives in Symmetry City for the first time, he finds the village in ruins, and infested with Podoboo Towers. Link then travels to the past to find the cause of the problem, at which point he notices the volcano inside the village erupting, wreaking havoc on the village. He then learns that the Tuni Nut, the village's sacred symbol, has broken. This causes instability in the village, thus the erupting volcano. To restore balance to the village, Link must bring the Tuni Nut to Patch atop Restoration Wall to have it fixed. Once the nut is fixed and placed on its pedestal in the Middle House, peace will return to the village. The volcano becomes inactive, and the present-day Symmetry City will no longer be in ruins. In the present, the raging volcano is replaced by a waterfall, parted in the middle by the entrance to Skull Dungeon.
In the present, inhabitants of Symmetry City claim to hear music flowing down from the mountains surrounding the village. In reality, the music comes from Tokkey, who is researching a tune for the Harp of Ages inside a cave on Talus Peaks.
Also in the present, there are two people who live on opposite sides of the village who are not identical twins. One claims he is too small, the other, too big.
