Looking west from the Carrowmore Megalithic Cemetery, the visitor's eye is irresistibly drawn to the magical mountain of Knocknarea, the Hill of the Moon, with the enormous unexcavated passage-grave known as Queen Maeve's cairn on the flat summit.
Visible from up to 50 kilometers in every direction, including several of the chambers in Carrowkeel, Queen Maeve's cairn is said to be the largest unopened megalithic monument left in Europe. It is certainly the most impressively located. The cairn is 60 meters in diameter and 10 meters high. The monument is constructed on a massive platform which contains many chunks of quartz.
