The superficial similarity in form of prehistoric standing stones and early medieval western British inscribed stones has sometimes led to the suggestion that the medieval stones were reusing the earlier monuments. In this paper this suggestion is critically assessed. It shows that the medieval stones are different in size from the prehistoric stones, and placed in different contexts. This lack of reuse of prehistoric standing stones is considered in the context of other examples of monument reuse known from western Britain.
