Ilex Forest shrine
The Ilex Forest shrine is a small structure located in the Ilex Forest, which it is named after, west of Azalea Town in Johto.
In the games
Generation II
The shrine is present in Pokémon Gold and Silver, but has no purpose. In Pokémon Crystal however, it is used to obtain the legendary Pokémon, Celebi.
When the player puts a GS Ball on the shrine, a level 30 Celebi will appear. The player then has the opportunity to capture the Pokémon.
Generation IV
The shrine is set to appear in the remakes of Gold and Silver. Screenshots have been released showing Gold interacting with a Pikachu-colored Pichu and the Notched-ear Pichu near the shrine, but its purpose in these games remains unknown, though likely to be similar to its Generation II function.
In the anime
In the anime, the shrine has appeared in the fourth movie, and briefly in A Farfetch'd Tale.
