This seminar will give an overview of the Future Circular Collider Feasibility Study. The luminosity-frontier electron-positron collider (FCC-ee) is part of the proposed Future Circular Collider (FCC) programme which consists of FCC-ee followed by an energy-frontier hadron collider (FCC-hh). This study is well aligned with the 2020 Update of the European Strategy for Particle Physics that requested a global feasibility study of a future 100 TeV hadron collider at CERN, with an electron-positron Higgs and electroweak factory as a possible first stage.  The latest accelerator layouts and beam parameters for FCC-ee and FCC-hh with the R&D for key technologies prepared for the mid-term review  will be presented.The progress in the interaction region and machine-detector-interface design, where the Italian contribution with INFN-Frascati has a well-established leading role will be discussed. Join Zoom Meetinghttps://infn-it.zoom.us/j/95274769209?pwd=cm82R2dsd3hxZ2Q3VTVsMGhOQ3dQdz09Meeting ID: 952 7476 9209Passcode: 774691
