Tim Berners-Lee was originally in the office on the right (with the below sign on it) and then moved to the one on the left with the world’s first web server, at CERN in Switzerland / France (technically on the French side).
There’s no marking or anything on the doors, and they’re just used as normal offices by CERN. The people inside looked confused we were so excited to be there and taking pictures. 🙂
