Relax and discover the wonders of space in our Sensory Space.

Take a stroll around our Astropark, which is 14 acres of attractive, landscaped grounds. Discover the scale models of the Solar System and the Universe and a wide range of flora and fauna. Of particular interest are the Human Orrery, two sundials, and historic telescopes and telescope domes.

The Armagh Observatory, founded in 1789 by Archbishop Richard Robinson, is a modern scientific research institute with a rich heritage. Our astronomers are researching Solar-System Astronomy, Solar Physics, Stellar and Galactic Astrophysics, and Solar System Earth relationships.
