The medieval core of Sheffield, as derived from Goslings plan of 1736 and descriptions contained in the Records of the Burgery. The medieval settlement would have been focused on the castle with the market place and cathedral also important loci. The town corn mill was situated at the edge of this area in Millsands. Sheffield Cathedral is one of only a handful of surviving medieval structures in the town centre. It is one of Sheffield’s major buildings contributing significantly to the character of the town. Beginning life as the medieval parish church, it became a cathedral in 1914. The eastern end, dated largely to the early 15th century contains re-used elements that appear to date from the 12th and 13th centuries. The original cruciform plan was heavily modified in the early 16th century when the Shrewsbury Chapel was added. The chapel contains the tombs of the 4th and 6th Earls of Shrewsbury, members of the powerful Talbot family. Further extensive alterations took place in the late 19th and 20th centuries. The churchyard extended further to the south originally but was shortened in 1866 and 1891 to allow the widening of Church Street. It was further reduced in 1994 during the construction of the Supertram network. The burial ground closed in 1856. The cross shaft of an Anglo-Saxon cross, dating to the late 8th/ early 9th century, was discovered reused as a trough in Sheffield Park in the 19th century and may have been the 'Great Cross' recorded as destroyed during the 1540 reformation and formerly standing in the churchyard (see SMR 253). This find may be indicative of some form of Saxon settlement. Sheffield Cathedral has, in one form or another, occupied this spot for at least 800 years. Legibility is, therefore, significant.
