Stone Keep Castle

A 15 by 15 three-floor stone brick keep with corner turrets, arrow slits and a roof walk.

A compact castle that works as a real survival base. Three wooden floors connect by a ladder in the corner, the ground floor has arrow slits and a 3-wide gate, and the battlements give you a lookout over the area. A few mossy and cracked bricks make it look aged.

How to build the Stone Keep Castle

  1. 1

    Base

    Lay a 15 by 15 stone brick floor.

  2. 2

    Outer walls

    Build stone brick walls 12 blocks high around the edge. Open a gate 3 wide and 3 tall in the middle of the front.

  3. 3

    Floors

    Add spruce plank floors at the 5th and 9th levels and a stone brick roof on top of the walls.

  4. 4

    Battlements and turrets

    Place merlons on every other block around the roof edge. On each corner build a 3 by 3 turret three blocks above the roof with its own merlons.

  5. 5

    Windows and slits

    Cut 1 by 2 arrow slits on the ground floor and add 2-tall glass windows on the upper floors on every side.

  6. 6

    Ladder

    In the back left corner, place a ladder against the back wall from the ground to the roof, passing through each floor.

  7. 7

    Weathering

    Swap about one in ten stone bricks for mossy stone bricks and a few for cracked stone bricks.

Builder tips

  • A stonecutter turns stone into stone bricks one for one.
  • You need about 25 stacks of stone bricks, so set up a cobblestone generator or mine a cave.
  • Arrow slits let you shoot out while mobs cannot path in.
