After the war ended, a small group of Jewish survivors restored the synagogue to its proper function.
However, the custodians soon left Poland due to the antisemitism of the communist authorities of the 1950s and 1960s; as a result, the synagogue ceased to operate.
The synagogue reopened on 11 September 2000, completely restored to its pre-war condition by the Auschwitz Jewish Center Foundation, at the cost of one million dollars.
The adjoining house was purchased by the foundation and turned into a contemporary museum called the Auschwitz Jewish Center (Żydowskie Centrum Edukacyjne).
