This paper outlines an investigation and describes strategies to capture, simulate and reproduce experiences originally designed for large-scale immersive architectures within Virtual Reality. Applications and experiences created for a specific immersive platform depend on the complex and costly technical infrastructure they were originally designed for. Descriptions and video documentation only go so far in illustrating an immersive experience. The embodied aspect, the emotional engagement and the dimensional extend, central to immersion, is mostly lost in translation. This project offers a prototypical implementation of a large-scale virtual exhibition, incorporating various immersive architectures and applications situated within a fictional 3D scene. The motivation behind this project is to provide a framework to showcase and for the conservation of immersive experiences and systems outside specialised facilities and labs. Furthermore, it presents a test-bed and space for experimentation to design and evaluate immersive experiences and architecture before they are developed at full scale.
