Building Domes in Minecraft
Domes are half-spheres that create stunning rooftop structures in Minecraft. They're commonly used for observatories, churches, capitol buildings, and greenhouse roofs. A dome starts with the widest circle as its base and tapers up to a single block or small circle at the top.
Use the layer slider to see each horizontal layer of your dome. Layer 0 is the base (widest part) and the last layer is the top. Build from the bottom up, placing each circle layer on top of the previous one. The tool shows you the exact block pattern for each layer.
For the best-looking domes, choose diameters between 15 and 40 blocks. Smaller domes look very angular, while very large domes require extensive material gathering. A 20-block dome is a great starting point for most builds.
