This museum is really fun, covering indigenous people of the area, the history of Cartagena and the navy. There are a lot of interactive displays which I am sure is great for kids. As others have noted, the text is largely Spanish only, so it took a while with Google translate (photo). As some of the text is on glass it was hard to read. I spent maybe 1.5 h in the museum and would have spent more if it wasn't for the language barrier. If there is a chance to have an English speaking guide, I would recommend that.
