Killowen

thumb|250px|Church of the Sacred Heart, Killowen Killowen (, now spelt Cill Eoin, alternatively spelt Cill Abhainn) is a small village in County Down, Northern Ireland. It is in the townland of Ballinran near Rostrevor and on the shore of Carlingford Lough. Ballinran is in the Electoral Division of Killowen, in Civil Parish of Kilbroney, in the barony of Iveagh Upper, Upper Half within the Newry and Mourne District Council area.

==History== In 1976, a court tomb known locally as the "Giant’s Grave" at Ballinran, near Killowen on the shore of Carlingford Lough, was excavated ahead of road widening works. The site, located on boulder clay over Silurian shale, revealed sockets for orthostats that confirmed the presence of a long north-south aligned gallery tomb with a circular forecourt at the northern end. Although no cairn or kerb stones survived, the segmented gallery, over 12 meters long, featured typical sills and jambs, and one portal socket still contained a fractured stone stump. While no intact burials were found, cremated human bone fragments were recovered from several sockets, likely remnants from when the orthostats were removed. Additionally, three flint flakes were discovered, one of which may be associated with the tomb’s original use.
