Armagh Observatory & Planetarium

Welcome to Armagh Observatory and Planetarium, Ireland's leading centre for astronomy education. A truly unique organisation, where research and education, history and heritage come together. The Armagh Observatory is the oldest scientific institution in Northern Ireland and the longest continuously operating astronomical research institute in the UK and Ireland. The foundation of the Planetarium on the same site by Dr Eric Lindsay greatly enhanced the organisation's public face and outreach activities. The combination of an active Observatory and Planetarium on the same site, carrying out a vibrant research, education and public outreach programme, together with their rich scientific history that is still embedded within its heritage, is truly unique.
