CERN lies at Border of France and Switzerland where both Nations made available 625 Ha (Hectare) of Land in which France contributed 515 Ha and Switzerland about 110 Ha. One Hectare Land is equal to One Square Hectometre or 0.01 Square Kilometres Land. Underground Construction of Tunnel in CERN is about 59 Kms Length. This is very Huge Construction involving World's Biggest Complex Machinery ever built by Humans for Understanding Deep Secrets of Nature through High Energy Experiments. A Great Achievement in Engineering, Technology and even Great Achievement and Advancements in Most Fundamental Research Field Quantum Mechanics.
