In the countryside just south of Dublin, the Ritz-Carlton Powerscourt is perfectly situated in perhaps the most spectacular heritage garden in Ireland. Hotel guests are welcome to stroll the 47 acres of Powerscourt Estate, which were developed over a span of 200 years by Sir Richard Wingfield and his descendants. The initial layout by architect Richard Castle took shape in the 1730s and was expanded by architect Daniel Robertson in the 1840s.
