Hiding a castle in plain sight is not an easy thing. But just off the roundabout on Whitebeam Road in Dublin 14 is Clonskeagh Castle, hidden behind a blanket of trees with the grounds of Dodderstown and Milltown Grove apartments behind it. Dating from about 1790, it once stood on a much larger elevated site than its current half-acre, and was approached by an avenue which is now Whitethorn Road. It was constructed for Henry Jackson, an industrialist who owned a successful iron business with foundries in both the city centre and at the River Dodder, not far from his Clonskeagh home. He became a prominent member of the United Irishmen, and was involved with various preparations for the 1798 rebellion, as his foundries manufactured pikes used in combat, along with iron balls used in the French cannons. His son-in-law Oliver Bond, who was implicated in the preparations, died in prison of apoplexy, after which Jackson moved to the United States with his wife and extended family.
