Terezin (Theresienstadt) is the name of a former military fortress and garrison town in the north of the Czech Republic. During WWII, the Gestapo used this now-peaceful town as ghetto, concentrating Jews from Czechoslovakia, as well as many from Germany, Austria, the Netherlands and Denmark. Though it was not an extermination camp, of more than 150,000 Jews who arrived there, about 33,000 died in the ghetto itself, mostly because of the appalling conditions arising out of extreme population density. About 88,000 inhabitants were deported to Auschwitz and other extermination camps. At the end of the war there were 17,247 survivors. Today, a portion of the town is a holocaust museum.
