Muenster’s cathedral St. Paulus is a big Romanesque building in the center of Muenster. I was very surprised to learn that half of it was built in the 9-th century, it was started at the time of Charlemagne. This makes the cathedral one of the oldest churches I have ever seen in Germany. Its facade looks quite strange, it had once a gothic portal, but now on its place there is just a wall and the entrance is on the side. Also the church has two big towers, which look quite identical, but actually the left one is a little bit taller and wider; this can be seen if you are (or have someone with you) really paying attention to details like that. I was lucky to have such friend with me. The interior is simple, but the church looks very magnificent inside.
