I have no real info on the museum (we didn't go in) or about any of the sculptures, but we spent a fair amount of time just taking in the detail of the sculptures.
Here's a link to the museum page (should be in English, but if not, you can change the language).
this was my absolute favorite
|another very cool one|
I didn't take a ton of pics but if you like these, you should check out the website. I'd definitely like to go in the museum next time.
