A Fence is a type of wall. As with other Walls, it blocks movement unless a Door or some other gap is provided. It is the cheapest available wall.

Fence is one of the four types of walls, the others being:

Tips and Tricks[]

  • A fence around the perimeter of the map can provide a cheap final measure to keep escaped prisoners in.
  • A fence is not as stable as a wall, which means more warmth will be let out by a fence which cools down your prison.
  • When a prison is created, it is advisable to place fences as soon as possible. They're cheap, and act as a wall for outside rooms (e.g. yard). However, the player should replace them with a better wall (e.g. perimeter wall, brick wall) or add more layers of them.
  • As you progress later in the game, it is better to spend the extra money for Perimeter Walls as they have a high durability rate and inmates will avoid digging or climbing them.


  • The Fence was formerly a type of border element.
  • It was free to place until Alpha 23, where it was changed to $3 a square.
  • Because the Fence is a material, it is impossible to change dirt texture under the fence.
  • As of Alpha 34, fences no longer slow down prisoners digging an escape tunnel.
  • As of Alpha 36, there is a random event that can occur where a random section of around 5-12 fences will collapse (subsidence)
  • Just like with walls, contraband can still be thrown over if it's within 10 tiles of the border.
