We pay a longer visit to the cathedral, which is scaffolded from the outside. The mighty, almost 9m measuring rose window was pressed out by a bad winter storm a few years ago and fell into the church. Today the restoration is in full swing. The cathedral combines different building epochs of the Gothic and was redesigned several times during its long construction period (start of construction 1176, completion 13th century). This can be seen, for example, in the transept that was created in the first phase, which is more typically early Gothic and consists of 4 "floors" of arches, columns and windows. (In contrast to a three-story structure in the entire rest of the church) Later during the construction, the decision was made to tear down the already finished choir again, because it seemed too faint-hearted and to replace it with a more splendid building. So you see, a wonderful mess of: we stop the work here and continue there and so on. In the overall picture, this is also noticeable on closer inspection of the little things. The two side aisles are actually crooked in the connecting arches to the transept in order to make the connection. We have never seen that before.
