Also known as the Portal Tomb, Poulnabrone Dolmen is one of Ireland's most photographed ancient monuments. The dolmen (a large slab perched on stone uprights) stands amid a swathe of rocky pavements, surprising even the most jaded traveller with its otherworldly appearance; the capstone weighs 5 tonnes. The site is about 8km south of Aillwee and visible from the R480. A large free parking area and excellent displays make it visitor friendly.
Poulnabrone was built more than 5000 years ago. It was excavated in 1986, and the remains of 16 people were found, as well as pieces of pottery and jewellery. Radiocarbon dating suggests that they were buried between 3800 and 3200 BC. When the dead were originally entombed here, the whole structure was partially covered in a mound of earth, which has since worn away. A highly informative Office of Public Works worker is often on duty, protecting the monument.
