The Galileo Galilei Institute (GGI), founded in 2005 by the partnership between the National Institute of Nuclear Physics (INFN) and the University of Florence, has been the first European Institute dedicated to organizing and hosting long-term workshops dedicated to theoretical physics of fundamental interactions. A Launching Committee was appointed to advise about scientific and management structures and suggest criteria for the formation of the Scientific and Advisory Committees. The members of the Launching Committee were David Gross, Giuseppe Marchesini, Alfred Mueller, Giorgio Parisi and Gabriele Veneziano (chair). The GGI was established in a building of the University of Florence on the historic hill of Arcetri, near the house where Galileo spent the last period of his life and died in 1642.

Since 2006 the GGI has been running on average three long-term workshops every year together with conferences and training or focus weeks. In addition, starting from 2013 four PhD schools have been organized every year on different domains of theoretical physics: string theory (this is the pioneering school organized at the GGI since 2008), theory of fundamental interactions, statistical field theory, nuclear and hadronic physics. In 2019 a fifth school on theoretical aspects of astroparticle physics, cosmology and gravitation has been added. Each school lasts two-three weeks during winter and aims at providing lectures on theoretical physics covering both basic as well as advanced topics. The courses of the GGI schools are officially part of the Italian PhD training program for the Universities that join the initiative.

In 2018 the GGI became "Centro Nazionale di Studi Avanzati dell'Istituto Nazionale di Fisica Nucleare" (National Center for Advanced Studies of INFN), once again in partnership with the University of Florence. The Institute thus confirmed its status as a reference point for the international scientific community and as a site dedicated to high-level training of young Italian and foreign researchers. The basic referent of the Center is the INFN National Scientific Committee for Theoretical Physics, which gives its full support to favour the activities of the Institute. Support to its initiatives is also provided by a grant of the Simons Foundation. Workshop proposals, every year, are selected by the GGI Scientific Committee.

Beside its institutional activities, the GGI hosts short term events like conferences, meetings and schools proposed by the international scientific community and selected by the GGI Council. In addition, a long-term visiting scientist program is active. Finally, researchers planning to carry on their research activity at the GGI on a regular basis can apply for the GGI Affiliated Membership.

In 2019, the "Galileo Galilei Medal" award was established. It is assigned every two years to one or more scientists who, in the 25 years before the date of the award, have achieved outstanding results in theoretical physics. The first recipient was Juan Martin Maldacena.

Cortona Young, the virtual conference showcasing emerging talents in Theoretical Physics related to INFN, has closed after three dense afternoons with 12 web-seminars, 24 video posters and lively discussions in 4 virtual rooms among over 150 participants. The best web-seminar award, consisting in a plenary seminar at Cortona 2021, has been assigned by the selection panel to Elisa Maggio from Sapienza University of Rome, who has brilliantly presented results on Gravitational wave signatures of exotic compact objects

Best video-poster award

The Cortona Young Organizing Committee assigned also two prizes for the best video-posters: to Chiara Signorile-Signorile from Torino University, with an original and very effective presentation on Dealing with Infrared singularities in perturbative QCD , and to Carlo Heissenberg, from Nordita & Uppsala U, on Black-hole scattering from amplitudes in any Dimension. A positive experience that has kept the tradition of Cortona alive in spite of the pandemics, and has provided enriching fresh energy for the whole community.
