Carrowmore is a large group of megalithic monuments on the Coolera Peninsula to the west of Sligo, Ireland. They were built in the 4th millennium BC, during the Neolithic. There are thirty surviving tombs, making Carrowmore one of the largest clusters of megalithic tombs in Ireland, and one of the 'big four' along with Carrowkeel, Loughcrew and Brú na Bóinne. Carrowmore is the heart of an ancient ritual landscape which is dominated by the mountain of Knocknarea to the west. It is a protected National Monument.
