Dunskey Castle, a picturesque ruin south of Portpatrick, dates from the mid-16th century, built by the Adairs of Kinhilt on the site of an earlier, destroyed castle. Though the new tower house saw additions in the 1620s, it fell into ruin by 1700, with its stone used for other buildings, and now stands as a dramatic cliff-top ruin popular with coastal path walkers, offering views towards Northern Ireland.
