This site was excavated by George Eogan
“The structure consisted of an alignment 235 yards long and having originally at least ninety-one uprights and a circle 16 feet in diameter that originally had eight orthostats.”
The circle and the alignment failed to produce any finds. Eogan suggested an early Bronze Age date for the site.
