Harestua Solar Observatory

Harestua Solar Observatory is a research and education facility located at approximately 588 meters elevation near Oslo. The installation combines an underground section with an above-ground tower equipped with telescopes and specialized instruments for observing the sun.

The facility was established in 1954 under the University of Oslo as a research center focused on solar science. It later transitioned to become a public science education center, expanding its role in the late 1980s.

The facility serves as a place where visitors and students can engage directly with astronomy and learn about solar science through hands-on observation. It has become an important part of how Norway shares scientific knowledge with the public.

The facility is most accessible by traveling from Oslo and checking opening times in advance before your visit. Keep in mind that elevation and weather conditions can affect visibility during solar observation sessions.

The site has an unusual asymmetrical design with 8 meters of underground structure and 12 meters of above-ground tower, specifically engineered for stable solar observations. This construction approach helps maintain consistent measurements regardless of weather variations.
