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.
Let's get Social
Our Historical Geography Research Group has been in Greenwich, London, this week attending the Observatory Networks Revisited meeting.
They`ve been joined by one of Volunteer Research Assistants, Malcolm, who has been instrumental in researching our historic telescopes! Meetings such as this provide a platform for our research, as well as an opportunity to connect with our colleagues and friends from @nationalmuseumscotland , @dias_dublin , and of course the host, the @royalmuseumsgreenwich.

☀️World Meteorlogical Day☀️
Today is World Meteorlogical Day. This morning, like every morning since 1795, our met officers were out taking the daily readings and keeping a log in our records.
Last year we celebrated 230 years of weather readings, and we`re proud that we have this record.

It`s the March Equinox, which means we are officially in astronomical Spring!
In the Northern Hemisphere we are entering into Spring, the Vernal Equinox. The Southern Hemisphere is entering into Autumn, the Autumnal Equinox.
On the day of the equinox, the Earth’s axis is perpendicular to the Sun’s rays, meaning that all regions on Earth receive about the same number of hours of sunlight. In other words, night and day are, in principle, the same length all over the world. This is the reason it’s called an “equinox,” derived from Latin, meaning “equal night.”
