A stone Iron Age grain millstone (quern) was found close by. Finds from this site include Roman period pottery and a gritstone quern. A large quern was discovered on the Lough Scur crannog in Ireland. It is not easy to produce flour from a saddle quern with unmalted grain. A rotary quern, iron-age pottery and fragments of Samian ware were identified. A later development was the rotary quern, which takes several forms. A broken or disused quern therefore can be seen as symbolic of death. This was the earliest type of rotary quern to appear in the British Isles.
