cathedral's copy of the Magna Carta as it was on loan in the United States. 21st century A major renovation of the West Front was undertaken in 2000. It was discovered that the flying buttresses on the east end were no longer connected to the adjoining stonework, and repairs were made to prevent collapse. Additionally, the stonework of the Dean's Eye window in the transept was crumbling, meaning that a complete reconstruction of the window has had to be carried out according to the conservation criteria set out by the International Council on Monuments and Sites. There was a period of great anxiety when it emerged that the stonework needed to shift only for the entire window to collapse. Specialist engineers removed the window's tracery before installing a strengthened, more stable replacement. In addition to this the original stained glass was cleaned and set behind a new clear isothermal glass which offers better protection from the elements. By April 2006 the renovation project was completed at a cost of £2 million. An announcement in January 2020 stated that since 2016, archaeologists had found over 50 burials during the renovations, including a priest buried with a chalice and paten. Among the artifacts recovered was a coin depicting Edward the Confessor who was king from 1042 to 1066. During the dig, sections of some extensively decorated Roman buildings and related artifacts were also discovered. Some of the Roman, medieval and Saxon objects were to be displayed at the visitor centre which was expected to open later in 2020. In 2022 the scaffolding of the Lincoln Cathedral was removed from its west front after 36 years. Maintaining the cathedral costs £1.6 million a year. Between 2006 and 2009, 200,000 to 208,000 people visited Lincoln Cathedral annually. In 2010 the figure dropped to 150,000, making it the 16th-most visited attraction in the East Midlands. The fall in visitor numbers was attributed to the cancellation of the Lincoln Christmas Market that year. The cathedral website states; "Everyone is free to enter and gaze at the glory of the nave; you can sit in the peace of the Morning Chapel or visit the shop. If you want to explore further, we do ask you to pay." The cathedral offers tours of the cathedral, the tower and the roof. The peak of its season is the Lincoln Christmas Market, accompanied by an annual production of Handel's Messiah.
