Monoliths
by qMace_
Monoliths is a Fabric world generation mod for 1.21.10 that adds huge square pillars to newly generated terrain.
What it does
Terrain generation in the mod draws on bugs from old Minecraft versions, including the infdev era, so new chunks can come out looking unusual. The main addition is a set of large square pillars, each about four chunks across, that rise out of the ground. The pillars can carry ore deposits, and the author notes that this extra generation can add lag on a busy server. A server running it needs every connecting player to have it too. Files are published for Fabric only, with 1.0.0 for 1.21.10 as the latest build from 2026-02-28.
Key features
Oversized square pillars
Square pillars about four chunks wide rise from the terrain in newly generated areas.
Ore deposits in pillars
Ores can appear inside the large pillars, placing deposits inside the structures.
Old-version terrain bugs
Terrain shapes borrow glitches and quirks from early Minecraft development versions.
