On August 14, 1945, the Franciscans from the Province of Our Lady of the Immaculate Conception took over the church and on September 1 of that year, his dedication was made. In 1974 works began to restore the Gothic character of the building - wooden balconies and plasters that obscured original details were removed. In 1962, the call of the Church of Our Lady Assumed to the title of Our Lady of Częstochowa was changed. At that time, the image of Our Lady of Częstochowa was placed in the main altar. Since 1992 the cult of Our Lady of Fatima, the Queen of Peace and Unity, has been developing in the Darłów church, whose figure on June 2, 1993 was crowned by Pope John Paul II during an audience in Rome
