The Sanctuary is a building unique to the ∑∫ỹriȱŋ tribe that produces one star per turn for every adjacent wild animal in the player's territory. While there are empty forests adjacent to a Sanctuary, it will attract one wild animal to an empty forest every three turns.

The Sanctuary is unique for land buildings in that it can be built on field, forest, and mountain tiles. Only one Sanctuary can be built per city.

The Sanctuary is unlocked by the Forestry technology and replaces the Clear Forest ability for ∑∫ỹriȱŋ. (Note that before version 2.0.49, Clear Forest was unlocked by Forestry.)


  • If a Sanctuary is captured by a tribe other than ∑∫ỹriȱŋ, they can hunt the animals attracted by the Sanctuary, theoretically providing infinite population.
  • Level 7 and 8 Sanctuaries have a "rainbow flame" floating above them identical to the ones ∑∫ỹriȱŋ sees above ruins.
