January 27 marks the 70th anniversary of the liberation of the Auschwitz-Birkenau concentration camp.
Check it out:

Located in occupied Poland, Auschwitz-Birkenau was the most infamous German death camp, in which over a million Jews, Romani, and others whom the Nazi regime deemed unfit for life were gassed and murdered.

The Telegraph reports that Auschwitz survivors “will lay wreaths and light candles at the so-called Death Wall at Block 11.” This year’s commemoration is particularly important because it will likely be the last time those who personally experienced the horror of that camp will be able to make the trek to visit for a major anniversary. The inhuman treatment of Auschwitz captives and the barbarity of the Holocaust serve as stark reminders of how savagery can exist and even thrive in a modern, seemingly civilized world.
