By the early 19th century the fabric of the church had fallen into disrepair. All the medieval furnishings were gone, and the interior was as Francis Bumpus later described it, "pewed and galleried to a fearful extent." Between 1818 and 1830, the tower and choir were restored by George Gwilt Jun. In his efforts to return the church to its thirteenth-century appearance, Gwilt removed the early sixteenth-century windows at the east end of the choir and, lacking firm evidence as to the original design, substituted an elevation of his own invention, with three lancet windows, and a circular one in the gable above. The transepts were restored, less sympathetically, by Robert Wallace. The Bishop's Chapel and parochial chapel were removed, but plans for the demolition of the retrochoir were averted, and it was restored by Gwilt in 1832.
