Greencastle

Greencastle is a castle in County Down, Northern Ireland. While it dates mainly from the 13th century, it had substantial 15th- and 16th-century alterations. It was originally surrounded by outer rectangular walls with four corner towers (ruins of some remain). It is likely to have been built by Hugh de Lacy, along with Carlingford Castle on the opposite side of Carlingford Lough, to guard the narrow entry channel to the Lough, and the ferry crossing between the two. The motte from the earlier wooden motte-and-bailey castle (possibly built by John de Courcy) is still on the seaward side nearer the point. According to one legend John de Courcy was married at Greencastle, but this may have been at the original motte & bailey castle. According to the information boards at the site it was held for the English Crown by Richard de Burgh, Earl of Ulster, from 1264 to 1333. It was attacked and taken by Edward Bruce, the brother of Robert, in 1316. This was in spite of one of Richard de Burgh's daughters having married Robert the Bruce himself. It was attacked at least twice by the Irish in the later 14th century but still maintained as an English garrison in the 1590s. In the 16th century it was held by the Earl of Kildare and then Nicholas Bagenal of Newry.
