Giant's Ring

The Giant's Ring is a henge monument at Ballynahatty, near Shaw's Bridge, Belfast, Northern Ireland. The site is a State Care Historic Monument and also a Site of Special Scientific Interest. The site consists of a circular enclosure, 180 m (590 ft) in diameter and 2.8 hectares (6.9 acres) in area, surrounded by a circular earthwork bank 3.5 m (11 ft) high.

At least three of the five irregularly spaced gaps in the bank are intentional and possibly original. East of the centre of the enclosure is a small passage tomb with a vestigial passage facing west. There were reports of other tombs outside the enclosure, but there is no trace of these.

A wall to protect the site was constructed under the supervision of local landowner Arthur Hill-Trevor, 3rd Viscount Dungannon in 1837. An inscribed stone tablet on the wall surrounding the site, which details Viscount Dungannon's interest, was carved by Belfast stone-carver Charles A Thompson c. 1919.
