Precedence is given to features considered to be characteristic of the Early Christian/pre-Reform era, such as enclosures, (especially circular or oval), cross-slabs, high-crosses, bullauns and raised areas — with round towers and church remains further down the list unless there is a strong case for doing otherwise.:eccl site - possible (St Brendan's, Church Lane)
