The monument consists of the remains of a chambered long barrow, dating to the early Neolithic (c. 4,200BC - 3,000BC). A long barrow is a roughly rectangular or trapezoidal mound of earth and/or stone, usually between 25m and 120m long, with a length exceeding twice its greatest width. The mound may be edged with a timber or stone revetment, and they contain one or more stone or wooden burial chambers at one end. This barrow is 95ft long. There are two evident chambers, Chamber A has no capstone and measures 10ft by 4ft wide. The east and west end stones are 3ft and 1ft 6 inches respectively and the chamber is floored with number of small stones. Chamber B as a capstone measuring 6 ft by 5 ft 6 inches. The side stones of the chamber may have been removed. Other chambers may have existed as there are upright stones protruding. The barrow is situated in a small grass field immediately 100 yds north-west of Ty-isaf farm.
The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are an important relic of a prehistoric funerary and ritual landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence. Chambered long barrows may be part of a larger cluster of monuments and their importance can further enhanced by their group value.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
