The Irish state has officially approved the following list of national monuments in County Sligo. In the Republic of Ireland, a structure or site may be deemed to be a "national monument", and therefore worthy of state protection, if it is of national importance. If the land adjoining the monument is essential to protect it, this land may also be protected.
Sligo is a coastal seaport and the county town of County Sligo, Ireland, within the western province of Connacht. With a population of 20,608 in 2022, it is the county's largest urban centre and the 24th largest in the Republic of Ireland.
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.
Knocknarea is a large prominent hill west of Sligo town in County Sligo, Ireland, with a height of 327 metres (1,073 ft). Knocknarea is visually striking as it has steep limestone cliffs and stands on the Cúil Irra peninsula overlooking the Atlantic coast. At the summit is one of Ireland's largest cairns, known as Queen Maeve's Cairn, which is believed to contain a Neolithic passage tomb. In recent years there has been concern that the ancient cairn, a protected National Monument, is being damaged by climbers. There are also remains of several smaller tombs on the summit. Knocknarea overlooks the Carrowmore tombs and is thought to have been part of an ancient ritual landscape.

It was probably built in order to protect the newly won possessions of Richard Óg de Burgh, 2nd Earl of Ulster, in County Sligo, some distance from an earlier motte.
