In the 13th century Henry III. began to rebuild the abbey--the choir, transepts and chapels of the present structure being entirely his work. Little remains of the Confessor’s Norman building (the first of this style built in England) except some parts of the cloisters and the Chapel of the Pyx. The trial of the Pyx took place in the former apartment until the recent removal of standard coins to the mint. The Jerusalem Chamber is also an important relic of the Benedictine monastery. It was built in 1363 by Littlington, who also rebuilt the abbot’s house. Henry IV. died within its walls. Henry V. gave the trappings of his coursers to the abbey--to be converted into vestments. In this reign the building of the nave was pushed forward and the Te Deum sung after the battle of Agincourt. Caxton set up his printing press in the almonry at Westminster during the reign of Edward IV. Henry VII. added greatly to the beauty of the building by annexing his chapel to the east end. During his reign, Skelton, the first poet laureate, sought sanctuary in Westminster, which is the last instance on record of a person claiming this right. Sir Thomas More was imprisoned in the abbot’s house in 1534--a few years before the Dissolution of the monasteries. The usual fate overtook the religious establishment at Westminster, but as in the cases of Chester, Gloucester, Peterborough, Oxford and Bristol, the monastic church was converted into a cathedral--and a new bishopric formed. Thirlby became the first Bishop of Westminster in 1540--but was translated to Norwich ten years later and the bishopric suppressed. In this transaction the abbey lost some property which came into the possession of St Paul’s Cathedral, a circumstance to which the origin of the well-known saying, “Robbing Peter to pay Paul” may be adduced. The shrine of the Confessor was re-established in 1557, the old constitution having been restored two years previously. In the reign of Elizabeth this was again annulled. In Henry VII.’s chapel the Westminster Assembly met in the 17th century, and through their misguided energy Presbyterianism was established as the national religion for a certain time. It is impossible to say what dire effects this Assembly might have wrought upon the welfare of the country.
