Landmark
CERN (European Organization for Nuclear Research) near Geneva is the world's leading research center for particle physics. Established in 1954, it is currently supported by 23 member states. Its most significant facility is the Large Hadron Collider (LHC), a 27-kilometer underground circular accelerator where protons collide at nearly the speed of light. The primary goal of the research is to understand the fundamental laws of the universe and the structure of matter. One of its most spectacular discoveries was the detection of the Higgs boson in 2012. Beyond fundamental physics research, CERN is also the birthplace of major technological milestones, such as the World Wide Web, developed by Tim Berners-Lee in 1989. The institution fosters international cooperation and hosts thousands of scientists from across the globe. Visitors can gain insights into the subatomic world at the Globe of Science and Innovation.
