Founded in 1790, the Armagh Observatory is the oldest scientific institution in Northern Ireland, and one of the UK and Ireland's leading astronomical research institutes. It sits, along with the popular Armagh Planetarium, on fourteen acres of beautifully landscaped gardens known as the Armagh Astropark. A walk through the Astropark is a stroll through the universe, where every three steps on the ground corresponds to 100 million kilometres in space. Accompanied by striking photographs, this book takes the reader on a walk through the Astropark and Observatory grounds, visiting the buildings, telling of their long and distinguished history, and even looking at the abundance of plant life that thrives in the surrounding woodlands.
