The ruins of Black Castle stand on a rocky headland looking out across Wicklow Town and the North Wicklow coast. Built around 1176 following the Norman invasions, Black Castle is another castle with a turbulent history, under frequent attack from the local chieftains, mainly those of the O’Toole and O’Byrne clans. The O’Byrnes burned it down in both 1295 and 1315. The castle managed to survive until around 1645, when it was attacked again and eventually demolished.
