I built an entire Gothic basilica with Opus 5.5, and I’ve open-sourced it. ⛪✨ Basilica of Celestial Light is especially close to my heart. I genuinely loved creating this church. Working on it brought me a real sense of peace, and being able to share it with everyone feels just as meaningful. Everything was created with Opus 5.5, entirely in code. No external assets: no imported 3D models, image textures, or audio files. The architecture, stained glass, landscape, lighting, and soundscape are all generated at runtime with Three.js. You can walk through the nave, visit the crypt, climb the bell tower, explore the gardens, or take the guided tour, all directly in your browser. The project is open source under the MIT license. Explore it, learn from it, change it, fork it, and make something of your own. I’d genuinely love to see what others create from it. Source code: Play it here: I hope you find a little of the peace I felt while creating it.
