Aerial view of CERN and the surrounding region of Switzerland and France. Three rings are visible, the smaller (at lower right) shows the underground position of the Proton Synchrotron, the middle ring is the Super Proton Synchrotron (SPS) with a circumference of 7 km and the largest ring (27 km) is that of the former Large Electron and Positron collider (LEP) accelerator with part of Lake Geneva in the background.

Assembly and installation of the ATLAS Hadronic endcap Liquid Argon Calorimeter. The ATLAS detector contains a series of ever-larger concentric cylinders around the central interaction point where the LHC's proton beams collide. (Roy Langstaff, © CERN)
View of the CMS (Compact Muon Solenoid) experiment Tracker Outer Barrel (TOB) in the cleaning room. The CMS is one of two general-purpose LHC experiments designed to explore the physics of the Terascale, the energy region where physicists believe they will find answers to the central questions at the heart of 21st-century particle physics.

The Globe of Innovation in the morning. The wooden globe is a structure originally built for Switzerland's national exhibition, Expo'02, and is 40 meters wide, 27 meters tall. (Maximilien Brice; Claudia Marcelloni, © CERN)

The ALICE Inner Tracking System during its transport in the experimental cavern and its insertion into the Time Projection Chamber (TPC). ALICE (A Large Ion Collider Experiment @ CERN) will study the physics of ultrahigh-energy proton-proton and lead-lead collisions and will explore conditions in the first instants of the universe, a few microseconds after the Big Bang.
