The village of Butterknowle lies in the Gaunless Valley on the edge of the Durham coal fields. Its name derives from a geographical fault.

Whilst many local buildings are of stone, Butterknowle had a small brick works. Every brick is recognised by the unique mark of the brick maker's thumb print seen here at the upper right hand side. Whilst the works have long since gone its bricks remain as a reminder.
