The astronomical observatories at Gornergrat were installed in the late 1960's in the two towers of the Kulmhotel 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, a bedroom, 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.
