A Dungeon Entrance can be built as a centrepiece for a Garden or Formal Garden in a player-owned house. It is, as the name suggests, used as an entrance to a player's dungeon. It can only be used to access the dungeon if the player has a stairway conjunction built below the garden. It can be accessed during challenge mode, which can be triggered by activating a lever in a throne room. It requires level 70 Construction and 1 marble block to build, and earns the player 500 Construction experience when built.
