Our Mission

The Organ Attics Foundation aims to keep alive the memories of the seven Jews – three couples and a baby – who, during World War II, found a safe haven in the Organ Attics of the Breeplein Church in Rotterdam, as well as of the families that helped and cared for them, at great danger to their own lives.

The Foundation wants to achieve this by establishing an centre for education and a professionally curated exhibition space in the Breeplein Church.

As a result, the foundation hopes, the heroic deeds and the courage shown long ago will now inspire young and old to conduct that safeguards democratic freedom in the Netherlands and beyond.
