Castleboro House is a former stately home in Clonroche, County Wexford, Ireland. It was built in 1770 by Robert Shapland Carew, father of Robert Carew, 1st Baron Carew, who was an Irish Whig Party politician and landowner.
The mansion has a troubled history. An accidental fire took place in 1840 and destroyed all but the west wing. It was rebuilt in 1858 and survived until 1923, when it was burnt down by local IRA (Irish Republican Army) supporters. The remaining estate was later converted to farmland and the ruins of the house still stand today.
