Minecraft Tower Generator

A perfectly round tower is just the same circle stacked, and getting that circle right by eye is the hard part. Set the width and height, add battlements, and build it one clean layer at a time.

Round towers look great and are a pain to build, because every layer is a circle and one bad row throws the whole wall off. This tool locks the circle for you and repeats it up the height, so the wall stays true from the base to the battlements. Fill it in for a solid cylinder, or keep it hollow to live inside.

What it gives you

A perfectly round wall at any width, hollow or filled.
Optional battlements for a castle-style crenellated top.
Adjustable wall thickness.
A 3D preview of the finished tower before you start.
Layer-by-layer view, since every layer is the same circle you can repeat with confidence.
Tap each block off as you place it and your progress saves.
Total and per-layer block counts, plus /fill and /setblock command export and a .schem download for WorldEdit and Litematica.

How to build it

Open the builder and set the width (how wide the tower is) and the height (how tall).
Turn battlements on for a castle top, and choose hollow or filled.
Check the 3D preview, then follow the layers and tap each block off in game as you place it.
