Echoo's Structures
by EchooWorks
Echoo's Structures adds new generated structures to Minecraft worlds, including underground hideouts, trading posts, ocean monuments and nether fortresses.
What it does
Structures from this mod generate in new worlds and in existing chunks, placing hideouts underground, trading posts on the surface, ocean monuments beneath the waves and fortresses in the Nether. Each type appears as a separate structure, so a world gains several kinds of landmarks to explore rather than one large addition. Because the structures are part of world generation, they show up as the terrain is created and do not need to be placed by hand.
The server must run the mod to generate the structures, while players may join with or without it installed. Builds cover 26.2 – 26.3 for Fabric, Forge, NeoForge and Quilt, with the 26.3-1.3 file as the latest release on every loader. The code is licensed under a custom license, so the project is not open source, although its source code is publicly available.

Hidden underground rooms that players can discover while digging through stone and caves.
Trading posts

Use cases
Exploring new worlds
Players who start a fresh world can find the added structures while travelling across new terrain.
Server adventure maps
Server owners can use the generated structures as points of interest for adventure play on a shared world.
Who it’s for: Players who want more landmarks in their worlds, and server owners who host survival or adventure play. Only the server has to run the mod to generate structures, so a server can add them while players join with vanilla clients.
How it compares
Just Another Structure Pack is a structure mod for 1.19 – 26.2 under All rights reserved and not open source; it is needed on the server, with the client optional. Better Cave Worlds is an open source mod under the MIT License for 1.19 – 1.21.10, where the server needs it and clients may skip it, so it targets cave generation rather than surface and sea structures. Echoo's Structures covers 26.2 – 26.3 only.
