A mysterious structure built into the side of a canyon, found in the area's lowest depths. It is well-preserved, resembling a temple with its intricate outer-carvings. Inside, the far wall bares a mysterious riddle in Unown script. Half-crumbling pillars bear the forms of different powerful Pokémon such as Volcarona and Dragonite. The area is only accessible by swooping down with a flying-type Pokémon.
