Somewhat off topic, but CERN has a fantastic science museum attached to it that I had the privilege of visiting last summer. There is of course Tim Berners-Lee's NeXT workstation, but also so much more. It is also the only science museum I've visited that addresses topics in cyberinfrastructure such as serving out massive amounts of data. (I personally get interested when I see old StorageTek tapes lol.) The more traditional science displays are also great. Check it out if you are ever in the Geneva area. It is an easy bus ride to get out there.
There are also free tours basically every day, without pre-booking. The itineraries vary, but usually one of the old accelerators (synchrocyclotron) and the ATLAS visitor centre are shown.
