You're standing at the Leviathan of Parsonstown, in the grounds of Birr Castle. First, look at those two tall walls. They're about twelve metres high and seven metres apart. Slung between them is a huge tube, more than sixteen metres long. From 1845 until 1917, this was the largest telescope in the world.
