The Cathedral Basilica of Our Lady of Amiens, or simply Amiens Cathedral, is a Roman Catholic church. The cathedral is the seat of the Bishop of Amiens. It is situated on a slight ridge overlooking the River Somme in Amiens, the administrative capital of the Picardy region of France, some 120 kilometres north of Paris.
The cathedral was built almost entirely between 1220 and c. 1270, a remarkably short period of time for a Gothic cathedral, giving it an unusual unity of style. Amiens is a classic example of the High Gothic style of Gothic architecture. It also has some features of the later Rayonnant style in the enlarged high windows of the choir, added in the mid-1250s.
Its builders were trying to maximize the internal dimensions in order to reach for the heavens and bring in more light. As a result, Amiens cathedral is the largest in France, 200,000 cubic metres, large enough to contain two cathedrals the size of Notre Dame of Paris.
The cathedral has been listed as a UNESCO World Heritage Site since 1981.
