It is essential not to forget those days when everything was just wrong. One hour‘s drive north of Prague there is a town called Terezín where a Nazi concentration camp used to be during WWII. We will visit the fortification complex originally built in the 18th century to defend the Kingdom of Bohemia. You can find out how the Nazis used to manage the Prague Gestapo prison in the small fortress, as well as the concentration camp for the Jews in the big fort. This trip is a must, especially for those who like to focus on the history of the 20th century.
