The Anne Frank House - This is one of those experiences that stays with you. It is almost impossible to comprehend what happened to the people who lived in the space you are standing in. An audio guide leads you through the many rooms of the house. Especially moving for us was being in the room Anne slept in, seeing photos she had glued to her walls that brought her a bit of joy. I felt humbled to be able to be in that space to reflect on the lives of the people that endured such horrors. If you ever find yourself in Amsterdam,  this is a unique experience and one that should not be missed.
