The CERN Large Hadron Collider (LHC) is at present the most powerful particle accelerator in the world. In the last ten years, the data collected in proton-proton collisions with energy in the center of mass up to 13 TeV correspond only to roughly 5% of the final expected integrated luminosity to be exploited by the experiments before mid 2030s. Both LHC and the experiments already exceeded all expectations with extraordinary performances to deeply study the Standard Model (SM) of Particle Physics and to explore the Beyond Standard Model (BSM) realm. A program to upgrade the accelerator complex, the detectors, the data acquisition and the computing framework to select and analyse the humongous expected amount of data is presently ongoing. After the discovery of the Higgs boson, the new phase of detailed studies of its properties has been launched. Precision measurements both in the Higgs and Flavour sector are complementary to searches of supersymmetric or exotic particles to unveil undiscovered BSM phenomena. Future high-energy colliders, now under consideration for the Update of the European Strategy of Particle Physics, could complement and extend the physics reach of LHC, facing new technological challenges but enabling the field to possible new surprises.
