The Cathedral of Munster is considered the emblem of the city for its medieval style from the 12th. and 13th. centuries. You can spend some time exploring it as there’s a lot to discover, like a hall lined with larger than life-sized statues of Jesus and the 12 Apostles on the south west side. Or how about checking out the Astronomical Clock, dating from the 1540s? This stop is totally worth it and you can still make time to walk around the city. The stop is for 2 hours. The rest of the time is for transportation.
