The church became listed in 1989 as "a prominent Gothic Revival church by a regional architect occupying an important Early Christian site". Since 2004 the church is now in the Parish of Penarth and Llandough. Irbic Cross In the graveyard of St Dochdwy's is a monument known as the Irbic Cross. St Dochau's grandfather was known as Erbin, and it is thought that the cross is probably a commemoration to him. The cross is around ten feet high and dates from the 10th century. It is built from Sutton stone in four moulded blocks, though the cross head is missing. References Churches completed in 1866 Grade II listed churches in the Vale of Glamorgan
