Armagh Observatory is a modern astronomical research institute with a rich heritage, adjacent to the Armagh Planetarium. Founded in 1790 by Church of Ireland Archbishop Richard Robinson, as part of an ambitious plan to found a university in the City, the Observatory is one of the UK and Ireland's leading scientific research establishments. Around 25 astronomers are actively studying Stellar Astrophysics, the Sun, Solar System astronomy, and the Earth's climate here. The Observatory's 14 acres (57, 000 m2) of landscaped grounds include sundials and historic telescopes, telescope domes and the Armagh Astropark. The Astropark is a scale model of the Universe, which you can stroll around and discover some of the amazing phenomena in our Solar System, our Galaxy, and beyond. Children can compare the relative distances and sizes of the rocky inner planets and the gaseous outer planets. Self guided tours.There is limited wheelchair access to the building.
