You can now study the Large Hadron Collider, examine its appearance in detail and estimate its scale thanks to the 360-degree video of the BBC television station hosted on youtube. Most of the material presented is dedicated to the Compact Muon Solenoid, one of the four main LHC experiments. The video allows you to walk through the collider tunnel, where the tube is located, inside which accelerated particles are moving, examine the structure of the CMS detector, its structure resembling an onion, and see the largest ever or created a superconducting magnet that provides the detector. The total mass of metal in a magnet is twice the mass of the Eiffel Tower in Paris. Google has also previously published panoramas of the LHC in its own Street View service.
