Built 1437-50 by Alice de la Pole, Duchess of Suffolk, as part of a complete ensemble of church, almshouses and school. The 11 almshouses are set round a courtyard encircled by a timbered cloister. From the courtyard a covered staircase and lobby lead directly into the church, where the residents were expected to perform daily prayers on her behalf in the chantry chapel of St John the Baptist. The almshouses are built of rubble limestone with tall brick chimney stacks. Each residence consists of a ground floor room with attic room above. There was also a warden's residence included, originally a priest separate from the church incumbent. Listed grade I.

Listed buildings and structures are officially designated as being of special architectural, historical or cultural significance. There are over half a million listed structures in the United Kingdom, covered by around 375,000 listings.
Listed status is more commonly associated with buildings or groups of buildings, however it can cover many other structures, including bridges, headstones, steps, ponds, monuments, walls, phone boxes, wrecks, parks, and heritage sites, and in more recent times a road crossing (Abbey Road) and graffiti art (Banksy 'Spy-booth') have been included.

In England and Wales there are three main listing designations;
Grade I (2.5%) - exceptional interest, sometimes considered to be internationally important.
Grade II* (5.5%) - particularly important buildings of more than special interest.
Grade II (92%) - nationally important and of special interest.

There are also locally listed structures (at the discretion of local authorities) using A, B and C designations.

In Scotland three classifications are also used but the criteria are different. There are around 47,500 Listed buildings.
Category A (8%)- generally equivalent to Grade I and II* in England and Wales
Category B (51%)- this appears generally to cover the ground of Grade II, recognising national importance.
Category C (41%)- buildings of local importance, probably with some overlap with English Grade II.

In Northern Ireland the criteria are similar to Scotland, but the classifications are:
Grade A (2.3%)
Grade B+ (4.7%)
Grade B (93%)
