The Crystal Cathedral

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.
