12 Round Minecraft Tower Designs
Round towers make any build look better. Here are 12 designs with the sizes that work, so you can plan them in the circle generator in seconds.
Round tower basics
Every round tower is a circle stacked upward. In the circle generator, set the diameter, choose Outline (or Thick for chunky walls), and set the Height. The total block count updates, and the .litematic download includes every layer.
12 tower designs
1. Wizard tower – 9 blocks wide, 30 tall
Narrow and tall with a pointy cone roof. Build the roof from shrinking circles (9, 7, 5, 3, 1) with 2 layers each. Purple or dark oak trim.
2. Castle corner tower – 13 wide, 24 tall
Thick walls (2 blocks) in stone bricks, with battlements on top: every other block on the top ring.
3. Spiral-staircase tower – 15 wide, 32 tall
15 blocks leaves a 1-block central pillar and a 2-block-wide stair around it.
4. Lighthouse – 11 wide at the base
Stack circles that shrink every 8 blocks (11, 9, 7), paint red and white stripes, and finish with a glass lamp room.
5. Grain silo – 11 wide, 20 tall
Iron blocks or smooth stone with a small dome roof of the same width.
6. Mage observatory – 21 wide
A short 21-block tower topped with a glass dome. Put an enchanting room underneath.
7. Elven tree tower – 17 wide
Oak or birch walls with leaf “spheres” sticking out of the sides. Make leaf balls with the sphere generator (7–9 blocks).
8. Watchtower – 7 wide, 20 tall
Small enough for early survival. Add a wider 9-block platform on top for the lookout.
9. Water tower – 15-wide tank on legs
A short 15-block cylinder raised on four 2×2 pillars, with a small dome on top.
10. Nether portal tower – 21 wide
Blackstone walls with a portal in the middle of the floor. 21 is odd, so the portal centres perfectly.
11. Mega keep – 31 wide, 50 tall
Thick walls of 3, floors every 6 blocks, and smaller 9-block turrets on the sides.
12. Ruined tower – any size
Build a full tower, then remove blocks in a jagged line from the top and add moss, vines and cracked bricks.

Frequently asked questions
What size should a Minecraft tower be?
7–11 blocks for small towers, 13–17 for castle towers with stairs, and 21–31 for big towers with rooms on every floor.
How do I make a cone roof?
Stack circles that get smaller: for a 9-block tower use 9, 7, 5, 3 and 1, two layers each. Use stairs on the edges to smooth it.
