* You cannot create a guard tower inside a building.
* Guard towers take up one tile, but will overlap about half a tile in a 3x3 tile area around the central tile.
* When attaching the last piececreating, make sure you are facing the tile you wish the tower to be created on. Guard towers can be rotated by the creator, so the initial rotation doesn't matter. They cannot be pushed or pulled.
* Guard towers on Freedom servers can't be constructed in a radius of 50 tiles of another guard tower.
** Error message when too close: {{event|inline|You can't continue the tower now; another tower is too near.}}
