The Metsovion Interdisciplinary Research Center (M.I.R.C.) was founded in 1993 by the National Technical University of Athens (NTUA). Since 2015, it is an interschool laboratory of the NTUA. Its establishment and operation constitutes a symbolic act of paying back a part of the debt of the NTUA to the homeland of its founders and great benefactors. It is the sole research center in Greece which is specialized in mountainous regions, in a country with a surface over 70% mountainous. M.I.R.C. aims at the revival of the mountainous Greece on a sound basis, the equal participation of mountainous and remote societies to the opportunities for development and the protection of the fragile ecosystems. The advancement of the knowledge about mountains is a worldwide priority, today. The mountains of the world suffer, to a great degree, from the same problems, the confrontation of which is essential for the equilibrium of the planet.
