Terezin (Teresienstadt) , a peaceful little town one hour north of Prague. has been turned by the Nazis into a ghetto for the jews of Czechia and adjacent countries during World War Two.
Outside of the small fortress (Mala Pevnost - built in the 18 century on the edge of the town of Terezin) , near the entrance, there's the National Cemetery , dedicated to the victims of Terezin prison and concentration camp. Buried here are people exhumated from the mass graves within the fortress, urns containing ashes from the Crematorium of the Ghetto, and also remains of the dead from the Ghetto. In all, 10,000 victims (jews and other nationalities - and there 's a Cross and a David's Shield on the spot).
I believe , a visiti to places like Terezin (Czech Republic) , Dachau (Germany), Auschwitz (Poland) gives one a new perspective to the concepts of Life and Death; it teaches a lot about Human Nature , about Evil and Suffering. After visiting places like the above mentioned , one's view of the world ceases to be romantic , and becomes more lucid and realistic.
