When the Protestant church at Zamkowy Square in Bolesławiec was handed over to Catholics on 11 June 1968, it turned out to be approximately 70 percent destroyed. Practically all that remained intact were the walls and the tower standing beside them. There were no doors or windows; the interior and exterior plaster was 70 percent damaged, the roof truss and beams 35 percent damaged, and the walls had losses of up to 40 percent in several places as a result of leaks. The floors, electrical and lightning-protection installations, and interior furnishings had been completely destroyed.
Nevertheless, renovation work began with tremendous commitment and dedication. It continued from dawn until one o’clock, and often even later into the night. Work was carried out simultaneously inside and outside the church. Canon Edward Bober was always present among the workers, encouraging them not only with words but very often by his own example. He would change into work clothes and sometimes perform the most arduous tasks alongside the workers.
After the essential preliminary work had been completed, the renovated church was officially inspected on 23 December 1969. The report stated that there was no threat to public safety or health. On the basis of this decision, the church was opened for the faithful, and the following day pastoral activity was inaugurated with Holy Mass—the Midnight Mass.
The following days brought further events. On 1 January 1970, Father Bober was recalled by the Archbishop's Curia from his position as cooperator vicar at the Parish of the Assumption of the Blessed Virgin Mary and appointed rector of the Church of Our Lady of Perpetual Help, at which an independent pastoral centre was established at the same time. The boundary between the mother parish and the new centre ran along the following streets: Kościuszki, Dzierżyńskiego, Rynek as far as Kutuzowa Street, Komuny Paryskiej and Armii Ludowej. Bożejowice, Otok, Rakowice and Łąka were also attached to the centre. To assist with pastoral work, the Curia in Wrocław sent two vicars: Father Stanisław Miętus and Father Franciszek Opara. Father Miętus lived with the Adorers sisters on Zgorzelecka Street, while Father Opara and the rector lived in the sacristy of the church under renovation.
Meanwhile, further work on the reconstruction of the church continued at a rapid pace. New galleries were built inside, with all the old timber replaced. New ceilings and soffits were installed in both side aisles, and eight damaged load-bearing posts supporting the vaulting of the side aisles, the nave and the entire roof were replaced. In a separate part of the church, a parish office and living quarters were built. Electrical, water and sewage, and gas systems were installed. New windows, doors and floors were fitted, and central heating was installed. Three catechetical rooms were built and equipped, after which the entire church was plastered and whitewashed. Services were held every day during the renovation. The makeshift altar moved throughout the church interior, being relocated as the work progressed.
The enormous effort invested made it possible for Archbishop Bolesław Kominek to consecrate the church on 18 April 1971. During the ceremony, held in a church filled to capacity with the faithful, Archbishop Kominek emphasized the need for new churches and expressed his gratitude to the faithful and to Father Edward Bober for the reconstruction. It should also be added that on 25 October 1971, Father Bober received a prelature from the Holy See, which thus rewarded his effort and commitment.
It was not long before the new parish was canonically established. Created by the Wrocław Curia as of 1 July 1972, it was placed under the patronage of Our Lady of Perpetual Help. At that time, the following streets were also added to the parish: Nowotki, Wybickiego, Krasickiego, Drzymały, the other side of Kubika Street and one side of Karola Miarki Street. The administrator of the parish was the church's previous rector, Prelate Edward Bober, MSc.
