Winchester, who had been clerk of works at Windsor Castle from 1356 to 1361. On 29 August 1390 Yevele was made exempt from jury and other forms of service on account of his official duties and "great age". Yevele's work for other lay patrons belonged to the 1370s and 1380s. For John of Gaunt he carried out in 1375 unspecified works at the Savoy Palace in London and, together with another mason, Thomas Wrek, he contracted for the duke's large and very sumptuous canopied tomb in Old St Paul's Cathedral. For John de Cobham, 3rd Baron Cobham, he furnished the design ("devyse") for a new south aisle at the London parish church of St Dunstan-in-the-East, although he did not take charge of its building. From 1368 he served as one of the two wardens of London Bridge. Although the wardenships were purely administrative, it is highly likely that he was the designer of the two-storeyed apsidal chapel of St Thomas, which projected eastwards from the middle of the bridge and which was under construction between 1384 and 1397. The chapel possessed a "table" or handboard containing a summary history of the bridge, which was the source of the statement by the 16th-century antiquary John Leland that "a mason beinge master of the bridge howse", built the chapel at his own expense. This notice can refer only to Yevele, whose name presumably meant nothing to Leland. Death Yevele died in 1400 and was buried at the church of St Magnus the Martyr by London Bridge. His monument was extant in John Stow's time (the late 16th century), but was probably destroyed by the Great Fire of London. Work Works that can be attributed to Yevele with a reasonable level of certainty include: Kennington Manor (part, 1358, destroyed) Bloody Tower of the Tower of London (1361) Abbot's House and College Hall, Westminster Abbey (1362) Nave and west cloister, Westminster Abbey (1362) Palace of Westminster clock tower (1365, destroyed) Parts of old London Bridge (destroyed) London Charterhouse (1371) The high altar screen of Durham Cathedral (1372–80), shipped in boxes from London to Newcastle Savoy Palace (part, 1376, destroyed) West Gate, Canterbury (1378) The east and south walks of the cloister of St Albans Abbey (probably begun c.1380) (not mentioned by Harvey) The south transept façade of Old St Paul's Cathedral (1381–8) (not mentioned by Harvey) Old St Dunstan-in-the-East (part, 1381, destroyed) Rochester bridge
