For seventy-two years, the largest telescope on Earth sat in the grounds of an Irish country estate. Not at a royal observatory. Not in a purpose-built facility. In the gardens of Birr Castle, County Offaly, surrounded by box hedges so ancient they hold a Guinness World Record for height, the 3rd Earl of Rosse built a 72-inch reflecting telescope in 1845 and called it the Leviathan. It could capture more light and resolve more detail than anything humanity had ever pointed at the sky. Charles Babbage came to see it. So did a French prince. For decades, the boggy midlands of Ireland were the unlikely center of world astronomy.

William Parsons was obsessed with the heavens. Between 1842 and 1845, he designed and built the Leviathan of Parsonstown, a reflecting telescope with a 183-centimeter mirror -- the largest in the world. No institution funded it.
