Not a very rare UNESCO site for me, but again a different card. It was send from Germany and it has traveled a distance of 199 km in 10 days. It shows is the Zollverein Coal Mine Industrial Complex in Essen.
My name is Lisan and I live in Netherlands. I'm participating in a project called Postcrossing since March 2009. I created this blog to share my experiences with exchanging postcards all over the world and the project itself :) You can see my profile here
