Portbraddon Cave

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 5 m (16 ft) above the present-day high water mark makes it important archaeologically, as it would have been inhabited as far back as the Mesolithic.[1]

In the 1930s the cave was the subject of an archaeological dig by Andrew McLean May, who made a number of notable finds. During the course of the excavations, which went as deep as 2 m (7 ft) below the modern floor level, May encountered: iron objects, including the barrel of a muzzle-loading pistol; pottery and flint tools, some of which showed Mesolithic characteristics; fireplaces and animal bones and ultimately the original water-worn floor of the cave. Most notably May also discovered partial remains of three human females.[1] They were examined by Professor Thomas Walmsley at Queen's University Belfast, who noted that "most of the bones have primitive features which are not likely found together in post-medieval time; and there are some characteristics which suggest an epi-palaeolithic inheritance."[2]

The whereabouts of the human bones have since become unknown, and they have not been subjected to modern radiocarbon dating techniques.[1]
