As I just noticed, the placemarks in the 'Google Earth Community' -> 'Google Earth Community Forums' folder have been updated with the latest french version of the World Heritage List.

The english version, that can be found under 'Google Earth Community' -> 'Community Showcase' however, was not updated. I will wait for a few more weeks, then I will try to contact one of the moderators on how to update those placemarks too.

So for the most recent version it is always best to download the placemarks from the first post.

Enjoy!
