 At the west end of the Lower Ward is the Horseshoe Cloister , originally built in 1480 , near to the chapel to house its clergy . It houses the vicars @-@ choral , or lay clerks of the chapel . This curved brick and timber building is said to have been designed to resemble the shape of a fetlock , one of the badges used by Edward IV . George Gilbert Scott heavily restored the building in 1871 and little of the original structure remains . Other ranges originally built by Edward III sit alongside the Horseshoe , featuring stone perpendicular tracery . As of 2011 , they are used as offices , a library and as the houses for the Dean and Canons .
