The Armagh Observatory was founded in 1789.
The first astronomical obsevations at the site were made utilising sun spots.
The building is situated in what is now known as the Armagh Astropark, which also contains the Armagh Planetarium.
A number of notable advances in the realm of astronomy and weather predictin have been made at the Armagh Obervatory, including the invention of cup anemometer.
The Observatory is still operational today with roughly 35 astronomers in its employ. In 2019 the Observatory reached the milestone of having 225 years of unbroken weather records, which are available online.
Today the Observatory and associated Planetarium are open to the public for tours.
