This great house stands on land that has belonged to the O'Conor clan for more than 1,500 years. The O'Conors were the kings of Connaught, and this is the current home of the O'Conor Don, a direct descendant of the last high king of Ireland. The house, built in 1880, is a combination of Victorian, Italianate, and Queen Anne architecture, with mostly Louis XV-style furnishings, plus antique lace, horse-drawn farm machinery, and other memorabilia. Its primary attraction, though, is the O'Conor clan collection of portraits, documents, and genealogical tracts 2,000 years old. Displays include an ancient harp said to have belonged to Turlough O'Carolan (1670-1738), a blind Irish bard who composed tunes still played today. The grounds, with terraced and woodland gardens, hold the O'Conor inauguration stone, similar to the Scottish Stone of Scone, held at Edinburgh Castle. You have to see the house by guided tour, but if you really want to see the place to the fullest effect, you can stay the night.
