Now I really can't recall a nicer evening than a walk around Český Krumlov connected with the legendary Rotating Auditorium, located in the open air in the romantic castle garden https://www.otacivehlediste.cz/
or at the Municipal Theatre https://www.divadlo.ckrumlov.cz/...ov/, with a wide-ranging programme.
I guarantee you will remember this evening for a long time.
