Visit Us
Armagh Observatory and Planetarium is Ireland’s leading centre for astronomical research and education, and one of the top attractions in the City of Armagh.
Our grounds, spanning around 20 acres of green space, are open 24/7 and provide many opportunities to get closer to both nature and space as well as some lovely views of Armagh.
The Observatory – featuring a number of historic telescopes – is both a beautiful Georgian building and an active research facility, so it can be admired from the outside, but it is only open to the public on scheduled tours.
Alternatively, a tailored group tour, Gold Tour, or Diamond Tour can be arranged for you; contact us for more details.
