The Riber Cathedral is an irreplaceable landmark, and looking up in any corner of the town will not disappoint you. This is a church of Our Lady, built in the Viking era in 1150-1175, and completed in 1225-1250, it is the first Christian church in Denmark, and it is also the best-preserved Romanesque building in Denmark. [Appearance] I have seen hundreds of churches less, and there seem to be not many small-town churches in three colors. The building materials of the cathedral include tuff, German sandstone and granite from the Rhine region, and I don’t know if it is related to a variety of stone materials. The color of the church is distinctive: dark red-meteorite-brick red. The two towers on both sides of the main hall are red and yellow, one side is pointed, one high and one short, although they seem to be pieced together, but they are closely integrated with the central hall, from the details of the design and the way of bricks. [Inside] Two consecutive days because of early departure and late return, I could not enter the visit. The day I left was Sunday. I dragged the box and asked the uncle of the guard for a long time. I let me enter the door and look inside for five minutes. If you have time, it is recommended to climb the tower, overlook the red roofs, overlook the Riber River and grass beaches.
