Since arriving in Germany, by far the most memorable thing we have seen was the concentration camp at Dachau. It is a testimonial of how crazy the world can get and of how important it is for us to remain vigilant to keep things like this from being repeated.
Every generation and every war has the potential for atrocities like this to happen. Thankfully, this memorial to those who died and suffered during these extreme times reminds us of how cruel humankind can become.
