Christine Wilson was installed as Dean on 22 October 2016. Context_2 : Lincoln Cathedral or the Cathedral Church of the Blessed Virgin Mary of Lincoln, and sometimes St. Mary's Cathedral in Lincoln, England is the seat of the Anglican bishop. Building commenced in 1088 and continued in several phases throughout the medieval period. It was the tallest building in the world for 238 years (1311–1549), and the first building to hold that title after the Great Pyramid of Giza. The central spire collapsed in 1549 and was not rebuilt. The cathedral is the third largest in Britain (in floor area) after St Paul's and York Minster, being 484 by . It is highly regarded by architectural scholars; the eminent Victorian writer John Ruskin declared: "I have always held... that the cathedral of Lincoln is out and out the most precious piece of architecture in the British Isles and roughly speaking worth any two other cathedrals we have." Context_3 : The Lincoln Cathedral Library is a library of Lincoln Cathedral, Lincolnshire, England. Context_4 : Robert Bloet (sometimes Robert Bloett; died 1123) was Bishop of Lincoln 1093-1123 and Chancellor of England. Born into a noble Norman family, he became a royal clerk under King William I. Under William I's son and successor King William II, Bloet was first named chancellor then appointed to the See of Lincoln. Continuing to serve the king while bishop, Bloet remained a close royal councillor to William II's successor, King Henry I. He did much to embellish Lincoln Cathedral, and gave generously to his cathedral and other religious houses. He educated a number of noblemen, including illegitimate children of Henry I. He also was the patron of the medieval chronicler Henry of Huntingdon, and was an early patron of Gilbert of Sempringham, the founder of the Gilbertine monastic order. Context_5 : William George (died 1756) was an English churchman and academic, Provost of King's College, Cambridge from 1743 and Dean of Lincoln from 1748. Context_6 : The Old Bishop's Palace is an historic visitor attraction in the city of Lincoln, Lincolnshire. When it was first built, in the late 12th century, it was at the centre of the vast Diocese of Lincoln, which stretched from the Humber to the Thames. The Palace was one of the most impressive buildings of medieval England, reflecting the power and wealth of Lincoln’s bishops. It is situated on a spectacular hillside site, just below Lincoln cathedral, providing extensive views over the city. The site lies immediately to the south of the Roman wall which had become the medieval defensive wall of the "Bail", which enclosed both Lincoln Castle and Lincoln Cathedral. The palace was damaged during the Civil War and subsequently largely abandoned. During the period that followed the Bishop’s main residence was Buckden Palace in Huntingdonshire. In 1841, following the reduction in size of the Diocese of Lincoln, the Bishop moved to Riseholme, to the north of Lincoln. This proved inconvenient and Riseholme was sold. In 1886 an older building on the western side of the Palace enclosure was substantially rebuilt and enlarged in a Tudor revival style by the architect Ewan Christian. A further change occurred in 1888 when the architects Bodley and Garner rebuilt and converted the southern portion of the medieval Great Hall into a chapel for the Bishop. Context_7 : Colin Walsh is an English organist, who has played many recitals in various religious venues in England as well as two at the Royal Festival Hall. He has also played in many European countries and New Zealand, Australia, Canada and the USA. Some of his work has been released on the Priory label. He has worked as an organist or assistant organist at St. George's Chapel, Windsor Castle; Christ Church Cathedral, Oxford; Salisbury Cathedral (1978-1985); St. Albans Cathedral (1985-1988); and Lincoln Cathedral. In July 2002 there were plans to sack Walsh, whom The Telegraph described as "one of Europe's finest church organists", after differences with the Precentor, Andrew Stokes; however this plan was dropped and he was given a new role. Since January 2003 he has been Organist Laureate of Lincoln Cathedral. Context_8 : Abraham Haywood (1692–1747) was an architect who was born at Whitchurch, Shropshire and is likely to have come to Lincoln around 1720 to work for Francis Smith of Warwick on the construction of St Peter at Arches Church, Lincoln. In 1736 he built the town house of the Disney family, Disney Place in Eastgate Street, Lincoln and in 1744 the Lincoln Assembly Rooms in the Bail, Lincoln. He also built a house for himself on the east side of St Peter at Arches‘ graveyard on the site of the Lincoln Taylor’s Hall. Abraham Hayward’s younger brother John Hayward(1708-78), a mason by trade, also accompanied him to Lincoln. After Abraham’s death, he presumably continued the business and in 1753 rebuilt St Mary’s bridge in Lincoln. John Hayward’s grandson, William Hayward became surveyor to Lincoln Cathedral. Context_9 : The Nidaros Cathedral West Front ("Nidarosdomens Vestfront"), which includes multiple sculptures, was the final portion of the Nidaros Cathedral in Trondheim, Norway that was restored. This is the cathedral's main facade and one of the most beautiful and ornate portions of the church. The restoration of the west face structure took place from 1901 through 1969, and the last statue was erected in 1983. This part of the church is also the most recent of the original cathedral constructions; archbishop Sigurd Eindrideson laid the cornerstone for the west front in 1248. The construction was not yet complete when the church was burnt in 1328. The original design for the west face is not known, but one can assume that it was never built to those original plans; it is reasonable to assume that a screen front similar to that used elsewhere was planned on the west. Screen fronts were often rectangular and served as a cover to conceal the rest of the church. English cathedrals from the same period, among others Lincoln Cathedral, Wells Cathedral and Salisbury Cathedral, had similar fronts. The west front had three entrances and is flanked by two smaller towers on each side of the façade. Context_10 : William Haywood (died probably in 1823) was an architect who worked in Lincoln, England. His father John who died in 1817 was mayor of Lincoln twice and worked as a mason. Haywood succeeded his father as mayor after his death in 1817. His grandfather, John Hayward (1708–78) was also a mason in Lincoln. William Hayward's great grandfather was Abraham Haywood an architect of Whitchurch, Shropshire who came to Lincoln around 1720. William Haywood succeeded William Lumby as Surveyor to Lincoln Cathedral in 1799 and Edward James Willson followed him in this position in 1823. William Hayward also succeeded William Lumby as Surveyor for the Lincolnshire County County Committee, which had responsibility for Lincoln Castle and the prison. fact_1 : William George (died 1756) was an English churchman and academic, Provost of King's College, Cambridge from 1743 and Dean of Lincoln from 1748. fact_2 : The Dean of Lincoln is the head of the Chapter of Lincoln Cathedral in the city of Lincoln, England in the Church of England Diocese of Lincoln. fact_3 :  Christine Wilson was installed as Dean on 22 October 2016.
