Description : Rockmarshall Court Tomb is a court cairn and National Monument located on the Cooley Peninsula, Ireland. Rockmarshall has been settled since the Mesolithic (c. 5700 BC on); excavation of a midden shows late tools, oysters and periwinkles. The Carlingford Lough/Cooley Peninsula region was low in Mesolithic activity in comparison to Strangford Lough and Belfast Lough, due to the low quality flint. Carlingford and the Mournes could also have provided berries and nuts in season, and wild boar. A local population survived at Rockmarshall into the Neolithic, and the court cairn was built c. 3500 BC.
