Wells Cathedral is an Anglican cathedral in Wells, Somerset, commenced around 1175 on the site of a late-Roman mausoleum and an 8th-century abbey church. The cathedral has been described by the historian John Harvey as Europe's first truly Gothic structure, lacking the Romanesque work that survives in many other cathedrals. It is the seat of the bishop of Bath and Wells. This photograph shows the stairs leading from the north transept to the chapter house.Photograph credit: David Iliff
