    About

    Medieval Structures adds 36 generated structures to the Overworld and Nether, bringing medieval-inspired settlements, buildings, ruins, and exploration sites into the world without adding biomes or entities. Overworld examples include an fortified village with houses, a church, stable, castle, and defensive walls; a swamp castle with sewers; a snowy winter castle with secret rooms; and a hillfort representing an early medieval settlement. Other finds range from abandoned crop fields, taverns, mosques, graveyards, and a Viking tomb to forest hideouts, buried mines, and a merchant’s cart. The mod also adds a larger tri-dungeon with three spawners, as well as three dungeon types with entrances visible at the surface. In the Nether, players can encounter an apothecary stocked for potion-making, ruins intended to ease exploration, an abandoned bastion remnant, and the Hall of Withering.

    Written from CurseForge . How we write it

    In-game changes

    Does not change the game's code directly.

    Adds 60 structures.

    Counted from the names and data files in the mod, so the list may not be complete.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · Both latest files checked, last on 16 Oct 2026
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      2 latest files: the newest file for each Minecraft version and loader. Both are for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
    • Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · Both files read
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      The code of both files, for recent Minecraft versions. See each file in Releases

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files and images and found none.

    No sign of AI in the game

    We found no AI service, AI library or AI model file in its code.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
