First off the city is beautiful, a nice day trip. The cathedral connected to the castle is worth…read morethe $$$. Beautiful architecture & stain glass.
Now the castle. 10/10 would recommend the first room to the left. You put on these fancy slippers and it becomes an ice skating rink. I could spend HOURS in this room. Of course the rest of the museum is beautiful and offers a lot of information but man I would pay just to ice skate in that room every single day.
