Considering the Tinakilly Country House in Wicklow?

See Powerscourt Estate by Kay_C
This was once a castle built in the 1300's that was transformed into a mansion in 1731. The house itself is spectacular, but even more so are the beautiful gardens that stretch out for 45 acres. The view of the Wicklow Mountains makes you incredibly envious of anyone who ever lived here. Nearby is the Powerscourt Waterfall, the tallest in Ireland - a must see!
