Description
Summary Description and Reason for Designation
The following provides a general description of the Scheduled Ancient Monument.
The monument comprises the remains of two burial cairns probably dating to the Bronze Age (c. 2300 - 800 BC). The cairns were constructed using blocks of limestone rubble. Cairn A measures c. 18m in diameter and stands to a maximum height of 3m and Cairn B measures c. 10m in diameter and stands to a maximum height of 1.5m.
The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The monument is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits, together with environmental and structural evidence. 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 within which related evidence may be expected to survive.
