 In 1597 King Sigismund III Vasa gave order that the Protestants had to return all churches taken over by them in the past to the Catholics, including all accessories.The Protestants remained in possession solely of St. George's Church until in 1618 the base of the building was washed under by river Vistula, and the church had to be torn down.For a while they used once more the vacant Holy Spoirit Church, until in 1624 this building together with the hospital had to be handed over to nuns of the Order of Saint Benedict for the purpose of founding an affiliated institution.
