the card shows the Orlík Castle, near the Orlík nad Vltavou village (meaning, Orlík upon the river Vltava). The castle is surrounded by a huge castle park and a game preserve. It belongs to the house of Schwarzenberg, but normally during the summer it is open to public.
looks like a really lovely scene, and probably one of the most perfect views to greet you in the morning when you open your eyes and look out the window...
