windows on the south side, and single lancet windows in the west side. The Trinity Chapel has four large three-light windows on the south, and a seven-light window on the east side. The east window of the chancel has eight lights. Above the north vestry are three stepped lancet windows. To the east of the north transept is a "complex corner" with a variety of windows. The north transept itself has 12th-century pilaster buttresses, a small north doorway, and lancet windows. The north aisle has Perpendicular windows and a porch. Within the porch is another Norman doorway, with one order of shafts. Interior Arcades and furnishings In the opinion of the architectural historians John Newman and Nikolaus Pevsner, the nave arcades are "the finest piece of architecture in the church", each consisting of four wide bays, with semicircular arches. The oak ceiling of the nave has 15th-century carvings depicting birds, animals and angels. The Trinity Chapel contains a triple sedilia.

The Altar frontals were worked and embroidered by Beatrix Mary Pennyman, wife of the vicar, during the First World War. The octagonal font is Perpendicular, and is carved with arcading and (now headless) angels, The pulpit dates from 1853, it is polygonal, in stone, and designed by S. Pountney Smith. The floor of the church is tiled. The canopied clergy stall of 1897 was designed by C. E. Kempe; it was formerly in the chapel of Shrewsbury School. In 1729 John Harris and John Byfield designed and built a new three-manual organ to replace an earlier organ. This was rebuilt and enlarged in 1847 by Gray and Davison.
