 In the fifteenth century, two "splendid two-storyed Perpendicular porches" were added to the North and West aisles, the probable builder being Sir William Herbert, who was also building on a grand scale at nearby Raglan Castle.After the Dissolution of the Monasteries in the late 1530s, the priory church became the parish church of the town.Extensive restoration and new building occurred in 1884 when Thomas Henry Wyatt created a sanctuary by roofing over the crossing space next to the tower and added a further bay to the nave.
