A new episcopal 'cathedra' was provided and the flat plaster ceiling of the church was replaced with one of boarded wood in a gothic revival style.

Of the surviving medieval fabric, the blind arcading of the chancel is of particular note as are the north and south lancets and viscae of the East Wall.

There is a very fine medieval episcopal effigy by the font and the remains of some pillars of the quire arcade are to be seen in the walls to the west of the new chancel arch.

An earlier belief that the present cathedral was part of the nave of the older building was based on the existence of remains of a separate medieval church, on the same axis, some way to the east.

Giraldus Cambrensis, who was a contemporary eyewitness, specifically notes that the tomb in at Christ Church Cathedral, Dublin is only a replica.
