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 depicts the interior of Wells Cathedral's chapter house, built by unknown architects between 1275 and 1310 in the Geometric style of Decorated Gothic architecture.Photograph credit: David Iliff
