Between 2350 and 2400 metres above sea level, the Roque de-los Muchachos Observatory is a settlement of observatories on the slope of the Roque de los Muchachos on the Canary Island of La Palma.

The astrophysical observatories were opened in 1985. Several European countries are involved in the system, which is one of the most important of its kind worldwide. The climatic conditions on the highest peak of La Palma were decisive for the location of the project: on the mountain are many extremely cloud-free nights. Although clouds hang from 1000 meters above sea level often, but ends the clouds at the latest at 2000 meters, and the air on the Roque de los Muchachos is particularly clear.
