Portbraddon Cave (also spelled Portbradden, Portbraddan) is a relict sea cave located near Portbraddon, County Antrim on the north coast of Northern Ireland. Its location above the present-day high water mark makes it important archaeologically, as it would have been inhabited as far back as the Mesolithic. Read more on Wikipedia
