Portballintrae (in Irish: Port Bhaile an Trá, ie harbour of the settlement of the shore) is a small village in County Antrim, Northern Ireland, four miles east of Portrush and two miles west of the Giant's Causeway. Originally a fishing village, nestled around the horse shoe-shaped Ballintrae Bay, it was a cluster of whitewashed cottages nestling around the bay. Many of its earlier buildings have been restored and maintained. The original village houses were built in a line along the seashore and many old cottages still stand on the shore. The ruins of Dunluce Castle sit on the edge of a cliff between Portballintrae and Portrush. The castle was the main stronghold of the MacDonnell chiefs of Antrim.
