Guirguillano Observatory

Guirguillano Observatory is a self-built astronomical complex in the village of Guirguillano, in Spain's Navarre region, created over two decades by a group of dedicated amateur astronomers.

About Guirguillano Observatory

The site is energy self-sufficient and combines a passion for astronomy with practical outreach. It comprises a dome housing the hand-built 30-centimetre 'Sultán' telescope, a newer observatory building with a control room and a movable roof covering three further telescopes, and a ground-floor space used for shared meals during events.

Telescopes & research

Guirguillano's instruments include the 30-centimetre 'Sultán' telescope in its own dome, plus three additional telescopes housed under the newer building's retractable roof. The team collaborates on astronomy education and research projects and is a vocal advocate for dark-sky protection, reducing light pollution, and energy conservation.
