The gallery would have originally been covered with a cairn of stones but in most cases this has since collapsed. Its court is the largest in Ireland and it has two galleries, each containing two burial chambers. There is evidence of three of four burial chambers in the court. A trackway now runs through the tomb, making it difficult to discern the original structure. It too consists of a large court and two burial galleries.
Portal tombs are less elaborate than court tombs but many have a more striking appearance.
Erected about 2,000 BC, they consist of a single burial chamber formed by placing a large cap stone on several small stones. Like the burial galleries of the court tombs, they were once enclosed in a cairn of stones. This is the largest group of portal tombs in Ireland and it is of great archaeological importance. Researchers have suggested that the six tombs may once have formed a single massive monument. Fionn swore revenge and pursued them around Ireland.
