Ballowall Barrow is a Bronze Age chambered tomb, or cairn, near St Just in Cornwall, England, UK. Excavated in 1878 by William Borlase, the barrow is 72 feet (22 m) in diameter. The construction of the site is unique with a combination of Neolithic and Bronze age funerary rituals. A similar site was recorded by Borlase but its location has been lost.
The site today is a confused mix of original and reconstructions introduced by Borlase.
In 1999 there was some controversy regarding this site and others under the care of the English Heritage organisation. Members of a pressure group, the Revived Cornish Stannary Parliament, removed several signs bearing the English Heritage name.
