In October 1874 the first group of monuments, those on the Rock of Cashel, Co. Tipperary, was taken into State care. Since then, almost 1,000 individual monuments at 768 locations, have been taken into ownership or guardianship. These range from megalithic tombs of the neolithic period to medieval churches and castles, industrial mills and historic buildings of more recent times. One of the core functions of the National Monuments Service is to ensure the preservation of the monuments in its care for the benefit and enjoyment of present and future generations.
