Glebe Stone Circles, Stone circles in County Mayo, Ireland.

Glebe Stone Circles is a group of four stone circles in Glebe, County Mayo, about 3 km northeast of Cong and east of the R345 Ballinrobe Road. The circles lie close together within an area of roughly 90 by 180 m. The northern circle, about 14 m across, keeps 23 of its original 30 limestone stones, the tallest 1.2 m, with a low stone mound about 4 m wide inside. The largest circle is slightly elliptical, 17.5 m across, with 13 of 21 stones inside a low stone wall.

Edward Lhuyd documented these prehistoric monuments during a research journey through Ireland in 1699. His careful observations laid the foundation for understanding these ancient stone arrangements and their age.

William Wilde linked the circles to the mythical Battle of Moytura, and local tradition calls the surrounding fields Cath na bPunnán, "the battle of the sheaves." The four monuments are also known as the Nymphsfield Stone Circles, after the nearby glebe of Nymphsfield.

The site is reached by parking near the road and walking through open fields, so wear appropriate clothing for weather and uneven ground. The circles are spread across the countryside, making sturdy footwear a good idea for any visitor.

Edward Lhuyd measured the circles in 1699 and noted smaller inner circles inside two of them; William Stukeley later published his sketches. The group lies within a 90 by 180 m area, the largest but completely isolated group of Ireland's Western Series of nine stone circles.
