The Cathedral Character Area (view detailed map) is dominated by the cathedral at its centre, built largely during the High Medieval Era [850-1350 AD]. Many buildings face the cathedral around Minster Yard, the majority of which are associated with the cathedral. Together with the cathedral, these buildings form an ecclesiastical centre located on the northern escarpment overlooking the city. Much of the early townscape has survived and as a result the Character Area is a well-preserved example of a High Medieval religious centre, although several of the buildings themselves have been altered since then, especially during the 18th century.
