Terezín was a concentration camp established by the SS during WW II located in the German-occupied Czechoslovakia. Tens of thousands of people died there, some killed outright and others dying from malnutrition and disease. More than 150,000 other persons (including tens of thousands of children) were held there for months or years, before being sent by rail transports to their deaths at Treblinka and Auschwitz extermination camps.
