Carrowmore is home to the largest and oldest collection of stone circles and dolmens known from Neolithic Ireland. These monuments are also among the country’s oldest, with the oldest pre-dating Newgrange by 700 years. Archaeologists have recorded over 60 tombs of which 30 are visible.
Carrowmore is one of the largest megalithic cemeteries in W. Europe and the guides and diagrams there can explain the significance of the Dolmens, Passage graves and stone circles around the visitor centre. Radiocarbon dating suggests 3,800 and 4,600 BC for two of the tombs.
