Task: Question Generation
Input (English): Passage: Wells Cathedral is an Anglican cathedral in Wells, Somerset, England, dedicated to St Andrew the Apostle and seat of the Bishop of Bath and Wells, whose throne or cathedra it holds as mother church of the diocese. Built between 1175 and 1490 to replace an earlier church on the site since 705, it is moderately sized for an English cathedral. Its broad west front and large central tower are dominant features in the city and countryside. It has been called "unquestionably one of the most beautiful" and "most poetic" of English cathedrals. Its Gothic architecture is mostly in the Early English style of the late 12th–early 13th centuries, lacking the Romanesque work that survives in many other cathedrals. Building began about 1175 at the east end with the choir. Historian John Harvey sees it as Europe's first truly Gothic structure, breaking with the last constraints of Romanesque. The stonework of its pointed arcades and fluted piers bears pronounced mouldings and carved capitals in a foliate, "stiff leaf" style. Its Early English front with 300 sculpted figures, is described as a "supreme triumph of the combined plastic arts in England". The east end retains a rare amount of ancient stained glass. Unlike many cathedrals of monastic foundation, Wells has many surviving secular buildings linked to its chapter of secular canons, including the Bishop's Palace and the 15th-century residential Vicars' Close. The cathedral is a Grade I listed building.
