After World War II almost all Jews vanished from Poland. Only void remained. The signs of former inhabitants presence, typical for Poland, are marks of the mezuzot on the doorframes of the houses, now inhabited by new residents. These marks, holes are empty. „The mezuzot from this house” are new mezuzot, which are casts of these traces. Cast in metal, commemorate Jewish life that was going on there years ago, fill the emptiness. If you put a scroll inside, it will give a new life to mezuzot, which don’t exist any more. The mezuzot tell stories about traces from different places in Poland and it will probably disappear during next years. In this way it brings about the memory of the people who disappeared and is a kind of message from the world, which doesn’t exist any more. The mezuzot from the past get a new life and can be real mezuzot again.
