Before the Cairn was built, a stone lined grave box or cist was set into the ground. In this cist a dead child was buried together with a special earthenware pot. A capstone was then laid over the cist to seal it. The cairn was built and a ring of stone "kerb" weas placed around it.
Shortly after, part of the Dour Hill cairn was removed and another child and vessel were placed inside, the cist was sealed and the cairn replaced.
