How do you visit a railway station that no longer exists? 🚂

Hubert Schnedl rebuilt Vienna’s Nordbahnhof as a synthetic splat, vibe-coded a tour on top of it directly in Arrival and then hosted four live sessions as part of #TagDesDenkmals #EuropeanHeritageDays.

Visitors explored as avatars, discovered historical images and videos, and asked questions by voice - bringing a shared, human experience into a digital space.

Next live tours: Oct 18 or explore the permanent virtual tour at your own pace.

This started with a Gaussian Splat from @Schindelar3D and a few prompts.

Astra + Opus 5.5 handled the game dev, generating assets through @Blender and accessing our Splat relighting capabilities directly.

No additional app opened. All inside the browser and ArrivalSpace.

What would you add next?
