Although, walking back in time brings such a melancholy remembrance of one of the most challenging times in our history, Houston's Holocaust Museum offers an in-depth look at this period of history. Actual film footage, photographs, letters, and permanent exhibits, which include, Bearing Witness, that takes visitors back through pre-war, the Nazi movement and the “Final Solution” after the Holocaust; The World War II Holocaust Railcar, which is on display to demonstrate the kind of transportation that millions of Jews were forced to ride to the camps; and the Danish Rescue Boat is permanently featured to share with visitors about a rare heroic Holocaust story in 1943 when Christians in Denmark risked their own lives to save thousands of Jews from death. Oral histories of Holocaust survivors, including a number of Houston residents, are shown in the theater. Additional rotating exhibits are showcased at the Museum during the month. The Holocaust Museum depicts the dangers of hatred, marginalization, and fear that surrounded human beings during this time. There are exhibits that elucidate the development and operation of the ghettos, in which authorities compelled the city's Jews to live; the functions of concentration camps, extermination camps that were built primarily or exclusively for mass murder; and the execution of war criminals.
