Cadw's description

The following provides a general description of the Scheduled Monument.

The monument consists of the remains of a chambered long cairn, a funerary monument dating to the early Neolithic (c. 4,200BC - 3,000BC). A long cairn is a roughly rectangular or trapezoidal mound of 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.

The small rectangular chamber which measures 1.5m long and 0.6m wide is formed by five upright stones, of which only two are complete and are characterised by cup-marks. The large capstone now rests on only these southern uprights with its northern edge resting on the ground. The chamber is surrounded by a stony mound, which is accentuated by natural outcrops of rock with the remains of a kerb 2m further south.

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 environmental and structural evidence. Chambered long cairns 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.
