Ruins (Structure Spawning System) – add new structures to world generation!


Minecraft’s world is so exciting and interesting because it is random, and always new. Besides biomes, the generator also spawns several structures like dungeons, strongholds and more. Ruins, a mod by AtomicStryker (though based on d00dv4d3r‘s old mod from the beta days), aims to add more of these to your world. It comes with lots of cool included structures, but also allows a way to add your own! Let’s take a closer look.

Now, the mod itself is more of a system to add new structures, and if you look at it like that, it’s really not that interesting. However, it does come preloaded with a bunch of very interesting structures. In my travels, I encountered several, which all have unique uses in the game’s world.


Ruins like old broken-down houses and walls make exploration more rewarding and give the world that feeling of history and backstory you don’t quite know yet. Balloons grace the sky and make the world feel more alive and vivid with combinations of bright colors. Pirate ships spawn in oceans to make them more interesting to explore and less dull, though they provide no real challenge. Fountains and statues are scattered around the world adding a bit of beauty as well as mystery.


Giant towers pierce the sky and are filled with mob spawners as well as loot, making for an interesting gameplay addition not unlike dungeons in vanilla. Giant treehouses stand out in forests and make them more diverse. Even floating castles are here, and they make a very interesting location to visit, though I won’t spoil the surprise. ruins-mod-tower-inside

I could go on and on for even though I covered a lot of the structures included, there are more available to download online. People have been making their own structure templates for this mod for a while now, and some of them are very interesting. You can browse the mod’s thread on the forums to see some of them. A structure can easily be made for this mod by just making it in MCEdit, then converting it to ruins format with the provided converter. Hell, you could even download giant builds from PlanetMinecraft and use those in your world!


This is a very interesting mod. There’s not really a whole lot to talk about,  yet there is so much to see and even more to add on later. I recommend you give this mod a shot. You can get it here:
