Back from holidays, I imported the latest UNESCO data, which includes several corrections.
So, please re-download the
english version here, ou la
version franaise ici.
Enjoy!
P.S.: It's official: UNESCO now created their own GoogleEarth set! It is available here:
http://whc.unesco.org/en/list/kml/ (in french:
http://whc.unesco.org/fr/list/kml/ ). It is nicely done, and, of course, first hand data! You'll find some similarities, I think

. What's missing, are the sub-sites of properties with multiple locations. So I think, I'll still continue my work for a while - you decide which version you like
