The site is steeped in history and had previously had an Iron Age Fort built on it one thousand years earlier followed by a Norman castle. The interior of the castle was redesigned in the 18th century by two of the greatest architects of the time: William Chambers (Buckingham Palace, Kew Gardens, St James’s Palace, Trinity University, and Casino Marino) and, James ‘Athenian’ Stuart (best known for his pioneering role in Neoclassicism in the mid 1700’s.
