Terezin concentration camp was a Nazi-era facility located in what is now the Czech Republic. Established in 1941, it served as a ghetto for Jewish people and a transit camp for those being sent to extermination camps. Although it was presented as a "model ghetto," conditions were harsh, with overcrowding, inadequate food, and disease. The camp was also used for propaganda purposes, showcasing a false image of humane treatment to the outside world. Many notable artists, musicians, and intellectuals were imprisoned there, and some created works that documented their experiences, contributing to the historical understanding of the Holocaust.
