The oldest archaeological monuments in Ireland are megalithic (large-stone) tombs, in which the remains of our remote ancestors were buried together with pottery and items of flint, stone and bone. There are four main classes of megalithic tombs but the oldest two, dating mainly from c. 4000 to 3000 BC, are the portal tombs and the court tombs. Portal tombs have been so named because two tall portal stones flanked the entrance to the chamber.
