Classiebawn Castle
This magnificent "castle" in County Sligo is located on the west coast of the Republic of Ireland. We spotted it the day before as we were driving along the N17 headed to the city of Sligo and just knew we would have to circle back the next day to go find it.
Here's a bit of info about it from Wikipedia:
Classiebawn Castle is a country house built for The 3rd Viscount Palmerston on what was formerly a 10,000-acre estate on the Mullaghmore peninsula near the village of Cliffoney, County Sligo, in the Republic of Ireland. The current castle was largely built in the late 19th century.
