Cathedral Made Out Of Human Remains

Reformation
Prior to the Reformation all cathedrals of Western Europe were of the Roman Catholic Church. In England, the entire structure of the monastic and cathedral system was reconstituted during the Reformation. Cathedrals which were once Roman Catholic came under the governance of the Church of England. All the English monastic cathedral chapters were dissolved by Henry VIII and, with two exceptions, were refounded by him as churches of secular chapters of canons, with a dean as the head and with subordinate officers as minor canons.
In Germany and other parts of Europe, with the spread of the Lutheran Church, some ancient churches, like Nidaros Cathedral, Norway, and Lübeck Cathedral, Germany, became the seats of Protestant Bishops, as in England. Many new churches were built which serve the regional administrative function of a cathedral. However, not all churches that function as the seat of a bishop are known as "cathedral", the custom varying from place to place, according to local tradition. Some, like Budolfi Church which functions as the Lutheran cathedral of Aalborg in Denmark, are simply designated "church". Others, like Lübeck Cathedral, retain their ancient designation.
