Chapel Adjoining South Side Of St Mary'S School

The chapel adjoining the south side of St. Mary's School in Wantage was built between 1898 and 1899 by the architect Ponting. It is constructed of red brick in Flemish bond with limestone ashlar dressings and features an old tile roof. The chapel has a nave with an apsidal east end and a west porch that includes a vestibule. The porch is highlighted by a cross with a curved hood mould above a pointed multi-chamfered arch, which leads to double-leaf plank doors flanked by three-light lancet windows.

The taller gable wall behind the porch has a decorative canopy over a carving at the apex, above two late 13th-century style two-light windows set in multi-chamfered architraves. The gable wall of the chapel features a multi-chamfered pointed arch over a blue brick tympanum, which is adorned with an elaborate rose window. To the left, there is a Gothic crocketed spire. The five-bay side walls have pointed lancets with an ashlar band at sill level, and there is a lean-to roof over a passage with Diocletian windows to the left. The apsidal east end is supported by large offset and gabled buttresses, which have gabled roofs over late 13th-century style two-light windows with ashlar sills.

Inside, the apse features a wooden tierceron-vault, decorated-style sedilia, and canopies over statues flanking the east window. The nave includes a wall pulpit, linenfold panelling, original pews along the central aisle, a balcony to the west, and a barrel-vaulted roof. The vestibule to the west is framed by chamfered pointed arches, with decorative canopies over statues flanking a multi-chamfered pointed arch that leads to the double-leaf doors of the chapel. There is also a pointed cavetto-moulded doorway to the newel stairs on the left, and the chapel contains stained glass windows.
