The Castle is one of the most important buildings in a player's Turf. Upgrading it unlocks other buildings and new features, and increases the might of the player, among other benefits. The Castle is a fixed building, meaning its location is set from the start of the game and cannot be changed by the player.
When a player clicks their Castle, they are able to view statistics about their Castle Wall, troops, traps, and resources.
Castle Skins can be bought from the game's store to change its appearance and to grant the player buffs such as increased resource production or troop stats. This also affects its appearance in the Kingdom Map.
It is important to note:
- a player that has a level 6 or higher Castle can no longer use a Novice Relocator.
- having a level 10 or higher Castle allows a player's leader to be captured by other players.
- having a level 17 or higher Castle allows a player's leader to be executed if captured.
