If you’re visiting South Moravia, there is no way you wouldn’t eventually visit the town of Znojmo. I mean, how could you not? It’s historically and culturally one of the most important places in South Moravia and for a good reason! Znojmo is famous for its wine, pickles, history and beautiful architecture. You could say there is something interesting for everyone.
There are many beautiful places in the Czech Republic, but one can’t simply visit them all. Unless visiting interesting places is your job – then you may have the time to do so. It’s a shame but I think I might have a solution to your problem. Near the Austrian and Slovak border, there is an area where you can find some of the most beautiful châteaus in the Czech Republic, practically pristine nature and a lot of history stretching all the way back to the Moravian Empire. By the way, this whole area is on the UNESCO World Heritage List.
