The astronomical observatories at Gornergrat were installed in the late 1960's in the two towers of the Kulm Hotel Gornergrat. The rooms are leased from the Burgergemeinde Zermatt which itself is a member of the Foundation HFSJG. The Observatory Gornergrat South was rented to the University of Cologne, Germany, from 1984-2010. It includes a 7.5 m cupola, a computer room, a workshop, two bedrooms, a kitchen, and a bathroom. The instrument installed by the 'I. Physikalisches Institut der Universität zu Köln' was a high-tech 3 m radio telescope. From 1974-2005 the Observatory Gornergrat North was rented to the Italian Consiglio Nazionale delle Ricerche (CNR) in Rome and operated by the Istituto di Radioastronomia (IRA-CNR), sezione di Firenze. The Observatory Gornergrat North includes a 7.5 m cupola, two computer rooms. The instrument installed by the CNR/CAISMI was a 1.5 m infrared telescope. Both observatories are open for guest researchers. In addition to the two observatories, the Physikalisches Institut of the University of Bern operates a laboratory container at the Belvedere terrace for measurements of solar neutrons. This apparatus has been installed in collaboration with the Solar-Terrestrial Environment Laboratory of the Nagoya University, Japan, and is the European cornerstone of a worldwide network of solar neutron detectors.
