Out of over 500 cities I have visited in Europe, this site puzzles me the most in regard to why it has not been inscribed on the list yet. I believe it has been in nomination over 2 decades. The natural setting on which this cultural town sits is so unusual and therefore so mind-boggling. It has to be the politics, although I don't know the politics. Preservation works have been underway but would probably take years to complete. It's unfortunate that, since this town is located in the middle of nowhere with no ohter attractions nearby, very few foreigners visit this site. I'd say if this town were in Western Europe, say in France, it would be as big a tourist attraction as Mont-Saint-Michel or Carcassonne. So the town wouldn't get much money from tourists, either. It's all the more reason why the UNESCO should inscribe it and protect/preserve it as soon as possible.

Update 2017:

There is a bus that directly runs from Prague through Poland to Kamenets-Podilsk in western Ukraine. The two cities are the terminus of the line. This line goes through several WHSs, such as Wroclaw, Krakow, and Lviv.

There is also a bus that directly runs from Prague through Slovakia to Rakhiv near the Beech Forest WHS area in western Ukraine.

This may not be so surprising in light of the fact that the country of Czechoslovakia extended all the way to the current western Ukraine in early 20th century.
