Luttrellstown Castle, dating from the early 15th century (c. 1420), is located in Clonsilla on the outskirts of Dublin, Ireland. It has been owned variously by the eponymous and notorious Luttrell family, by the bookseller Luke White and his descendants Baron Annaly, by the Guinness family, the Primwest Group, and since 2006, by JP McManus, John Magnier and Aidan Brooks.
