Description

The Priory Church of St Mary and St Blaize was founded around 1117. It is constructed of flint with dressings of Lavant stone, Purbeck marble, and Caen stone rubble, and has a tiled roof. The surviving fabric includes the chancel with aisles, the central tower, the north and south transepts, the easternmost bay of the nave, and the south porch. The majority of this structure dates to the 12th century, although the chancel was rebuilt in the 13th century. Features include flying buttresses and a 14th-century porch. The main part of the nave was demolished in the 18th century. In the northwest corner of the north transept are the remains of three round-headed 12th-century arches belonging to the former priory cloister. Other features include a Perpendicular font and De la Warn Chantry, dating to approximately 1526.
