High CrossesThe heads of four High Crosses, dating to the 8th or 9th century, show the importance of Ferns as an early Christian monastic site, more than anywhere else in South Leinster. In the grounds of the Cathedral there are three heads, un-decorated apart from raised mouldings at the edge. The original bases have survived but the missing shafts have been replaced by concrete.
Another head is found in the ruins behind the Cathedral together with a stone with a raised cross. For detailed information, see Peter Harbisonís book on Irish Crosses.
