This 2700BC late Neolithic site is Belfast's very own small-scale Stonehenge and Ireland's largest ritual enclosure. The 200m-diameter site is enclosed by a 3m-high circular earthwork with five entrance gaps: climb to the top for great views of the surrounding city and countryside. In the centre of the earthwork stands a megalithic chamber with five standing stones and a tilted capstone. Experts believe the site was originally a meeting place or cult centre, and records indicate it was an 18th century venue for horse races.
