 The chancel of Gloucester Cathedral (c. 133757) and its latter 14th century cloisters are early examples.Four-centred arches were often used, and lierne vaults seen in early buildings were developed into fan vaults, first at the latter 14th century chapter-house of Hereford Cathedral (demolished 1769) and cloisters at Gloucester, and then at Reginald Ely's King's College Chapel, Cambridge (14461461) and the brothers William and Robert Vertue's Henry VII Chapel (c. 150312) at Westminster Abbey.
