The Armagh Observatory and Planetarium Legendary Telescopes Tour takes you on a journey through the Armagh Observatory to learn about its storied history and see its historic telescopes. Join your expert guide who will tell you about the history of the building and show you its telescopes and how they were used for pioneering science in their day. Listen to the unique stories along the way and discover why Armagh truly is a Celestial City.

Armagh Observatory opened in 1790 and is now a Grade A listed heritage building in which astronomers still undertake astrophysics research, and the oldest observatory in the UK and Ireland continuously in use for its original purpose. We have four generations of historic telescopes that remain in their original settings, as well as one modern telescope still used today.

Important notes:

The tour includes access to our grounds outside, so we recommend suitable footwear and clothing.

We make every effort to accommodate wheelchair users and others with mobility issues. If you would like to ask further questions about the tour in regards to access, please contact: reception@armagh.ac.uk

The start of the tour features a walk from the Planetarium Reception meeting point to the Observatory at the top of the hill, including an incline that may be a challenge for those with mobility issues. If that is a concern, let us know on the day or contact us in advance.

Due to the historic and listed nature of the Observatory building, indoor wheelchair access is only possible upon prior arrangement. The Planetarium building is fully accessible for visitors.
