Good size museum. The top floor has the best exhibits in my opinion. There are modern German collections that seem more relevant to Karlsruhe. The first three floors have a lot of ancient artifacts that you have seen in most museum, mummies, religious art, Greek pottery, etc. None of the exhibits have English translations, so all text in the museum is in German only. You can take a separate tour to the tower (turm) for an additional price depending on your desire to see the cityscape. The park behind the palace is really nice with lots of different areas, a small train, and plenty of walking paths. The area was full of people playing soccer, frisbee, and drinking while we were visiting. Overall a young vibrant city. My recommendations are to put the exhibit text in English like most museums do these days and make the signage on where to go for the museum tour more visible. It’s a bit easy to get lost at first. Coat check and restrooms are free. There is a parking garage under the plaza out front that makes getting to the palace very easy. Staff spoke mostly German, with a few that could speak a little English.
