After repeated Viking raids, the monks fled Lindisfarne in 875, carrying Saint Cuthbert's relics with them. The diocese of Lindisfarne remained itinerant until 882, when a community was reestablished in Chester-le-Street. The see had its seat here until 995, when further incursions once again caused the monks to move with the relics. According to local legend, the monks followed two milk maids who were searching for a dun-coloured cow and were led into a peninsula formed by a loop in the River Wear. At this point Cuthbert's coffin became immovable. This trope of hagiography was offered for a sign that the new shrine should be built here. A more prosaic set of reasons for the selection of the peninsula is its highly defensible position, and that a community established here would enjoy the protection of the Earl of Northumbria, as the bishop at this time, Aldhun, had strong family links with the earls. Nevertheless, the street leading from The Bailey past the Cathedral's eastern towers up to Palace Green is named Dun Cow Lane due to the miniature (dun) cows that used to graze in the pastures nearby.
