In the last years, there has been an abundance of AR applications developed, across multiple sectors. However, AR still remains in many domains just a buzzword, with very little evaluations carried out to study its impact on users in terms of exploration, navigation, learning and enjoyment. In this paper, we want to reflect on the use of AR on a heritage site related to World War II, to raise awareness around an issue, i.e., our common history, whose implications can still be felt today, in these days of social unrest. We want to show how an emerging technology like AR can do some social good by not loosing the memory of those who fought in the war and liberated Europe, now that many of us consider 'freedom' as a given. We will do so by presenting the story of George and Ursula Lévy, two Jewish children confined in Kamp Vught, a deportation camp for children in the South of the Netherlands, and by discussing in which way viewers of this story can be sensitized to 'not forget'.
