Built in 1730 on the ruins of Grace O'Malley's 16th-century castle, this charming Georgian mansion retains much of its original contents and has some stunning period-style rooms. The house is set in glorious gardens but the overall effect is marred by its commercial focus. Children love the Pirate Adventure Park , complete with a swinging pirate ship, a 'pirate's playground' and a roller-coaster-style flume ride through a water channel. It is 2km west of the centre.
