Carn Gluze which is also known as Ballowall Barrow is perched on a cliff edge near the village of St. Just in Cornwall.
Carn Gluze is an unusual multiphase site which was developed into a complex structure over time spanning the Neolithic and Bonze Ages (3500 – 2500BC). It usually described as a chambered tomb.
The site of Carn Gluze was hidden for many years beneath mine waste and was only excavated at the end of the nineteenth century. This work discovered that inside the barrow, or mound which was itself contained within two concentric ring walls there were five cists. Sone of the cist contained pottery and cremation remains dating from the Bronze Age.
