Little Structures

by MatBayern

Little Structures generates small ruins, watchtowers, a cave and an Illager outpost in the world, and the server needs it for them to appear in new chunks.

FabricForgeNeoForgeQuiltServer required, client optionalGNU Lesser General Public License v3.0 onlyOpen source1.19.4 – 1.21.8

What it does

The mod adds more than thirty subtle ruin structures that blend into the terrain, alongside vanilla-friendly remnants left by ancient builders. Several structures carry custom loot tables, so exploring them yields items that differ from standard dungeons. An Illager Watchtower, an Illager outpost, a Hobbit Cave, Nether Fossil sites and a Forest Dweller House are among the named additions, and the author lists more builds as planned.

Because the structures are generated by the world, the server must run Little Structures for them to appear in newly generated chunks. Clients can join without it, and the mod is published for Fabric, Forge, NeoForge and Quilt, with Fabric API required on Fabric. Files cover the 1.19.4 – 1.21.8 range, and the latest build, mc1.21.x-v2.1_mod, targets 1.21.8. The code is released under the GNU Lesser General Public License v3.0 only, so the source is open.

Key features

  1. Subtle ruin variations

    More than thirty ruin structures sit in the terrain without standing out from vanilla landscapes.

  2. Illager structures

    An Illager Watchtower and an Illager outpost add hostile-territory sites suited to exploration.

  3. Custom loot tables

    Several structures use their own loot tables, so chests hold items that depend on the structure found.

  4. Cave and nether sites

    A Hobbit Cave and Nether Fossil sites extend exploration beyond the surface and into the Nether.
