I've been to at least 4 human fossil sites around the world and that's only world heritage so there are probably a half dozen more and now I can add Wallonia to the list. I went to the small museum in Spy, assuming that the Spy Cave (cool name for either a Jason Stratham action flick or a Clive Cussler book.

I did not visit the cave itself because I believe it is off-limits and all items found inside have been moved already.

The museum has weird opening hours: Wednesday to Sunday only 13:00-17:00. They don't get many visitors. There is also not much English available with most in French and Dutch only. Hardly makes the 5 Euros worth it. Besides, as I mentioned before the addition of yet another human evolution site feels overkill, then a study to include only the main sites is needed because they just keep coming.
