The European Solar Telescope (EST) will be a 4-metre class solar telescope to be installed in the Canary Islands, aimed at understanding the fundamental processes occurring on the Sun. It will be optimised for studies of the magnetic coupling between the deep photosphere and the upper chromosphere. This will require diagnostics of the thermal, dynamic and magnetic properties of the plasma over many scale heights, by using multiple wavelength imaging, spectroscopy and spectropolarimetry. To achieve these goals, the EST will specialize in high spatial and temporal resolution using various instruments simultaneously that can efficiently produce 2D spectral information. The solar physics community involved in this project is currently collaborating under the EC funded I3 initiative SOLARNET and the H2020 GREST. These initiatives are promoted by the European Association for Solar Telescopes (EAST), constituted by partners from 15 European Member States, aiming to ensure access of European solar astronomers to world-class high-resolution ground-based  observing facilities, like the EST. Recently, EST has been included in the 2016 Roadmap of ESFRI (European Strategic Forum for Research Infrastructure).
