This project recreates Switzerland in Minecraft at a scale of one block per metre, using open geographic data from swisstopo. Its generated terrain places mountains, valleys, lakes, glaciers and other features in their real-world locations, including landmarks such as the Matterhorn, the Aletsch Glacier and the Grande Dixence dam. The full map covers 41,285 square kilometres, reaches 4,634 metres at the Dufourspitze and occupies a 24 GB download. It runs on Minecraft Java Edition 1.12.2 with the Cubic Chunks mod, which removes Minecraft’s usual height limit.
The world is generated from data rather than built by hand, so it is not a perfect replica: buildings are simplified, some features may be missing or inaccurate, and detail varies by region. Areas beyond Switzerland and some border zones use a coarser elevation model. A free, 1.1 GB Jungfrau-Aletsch version lets players test performance before buying; the full package costs at least 15 CHF, with future updates included. The project recommends a powerful computer with 16 GB of memory, and notes that new areas take time to generate on first visit. Instructions explain how to install the world through Prism Launcher, while an interactive map and teleport commands help players reach specific places and viewpoints.
