This is a beautiful church, with lots to see. Perhaps most well known is the Chapel of Bones, but ironically, it was the place where my family and I spent the least amount of time. It's fascinating, but only a single room. So in some ways, it was a bit disappointing.
However, upstairs there is a huge collection of nativity scenes from all around the world. There are hundreds of them, and it was absolutely amazing to see the different styles and interpretations of nativity scenes from different cultures. I eventually got tired, but my daughter would have easily spent hours looking at them all. I had to shuffle her along.
There is also a very small museum with paintings and other artifacts to view.
This is a great place to spend an afternoon. I came wanting to see the Chapel of Bones, not knowing any of the other things that were here, but I enjoyed everything else immensely.
The church itself is free to visit, while entering the Chapel of Bones requires the purchase of a ticket, which also includes seeing the nativity scenes and the museum. It's very reasonably priced and well worth it.
