The grain collected from the Volyn holdings was transported to Danzig or another port from where it was sold to the Netherlands, England, France, Italy, and Spain.

[6] At the time of the allotment of the land for the construction of the Bernardine monastery, Prince Janusz Zasławski professed Calvinism, and his wife, Alexandra Sangushkivna, belonged to the anti-Trinitarians.

The erection of the complex of the monastery in the newest style of Mannerism and Late Renaissance lights is associated with the construction activity in the exile area of architect Jakub Madeline, originating from Graubünden, land on the Italian-Swiss border.

It is during this period that historians date the western facade of the monastery building with its attic and typical Mannerist pediments preserved to this day.

With the beginning of the Cossack rebel under the leadership of Hetman Bohdan Khmelnytsky, the icon of the Zaslav Mother of God was evacuated to the Bernardine monastery in Rzeszow.

To equip the church during the period of 1766–1770, eight works of the outstanding 18th-century painter Szymon Czechowicz were purchased, in particular: St. Francis, St. Tadeusz, St. Onuphrius, St. Caetan, St. Vincent, the Transfiguration of the Lord, "St. Michael the Archangel", "St. Thecla", "St. Joseph" and "St. John of Nepomuk".

In June 1775, with a large crowd of worshipers, celebrations were held to mark the transfer of the image of the Mother of God of Zaslav to the main altar, as well as the crucifixion "surviving from the first foundation".

[14] In the 19th century, the Bernardine friars from Zaslavl owned a folwark with arable land and hayfields, a mill and stood in the village of Horodyshche, apiary in the Black Vine tract.

As a result of the policy to weaken the Roman Catholic Church in 1841, by order of the Russian authorities, the monastery was transformed into a "full-time 2-class", its clergy were cut off extremely, and its educational activities were abolished.

In the monastery's buildings, with the permission of the Russian government, there was novitiate for the united orders of Bernardine and Capuchin fathers, one for the entire Lutsk-Zhytomyr diocese.

Among those who were exiled at that time were Anthony Linevich, Felix Lubchinsky,[15] Marian Tokazhevsky, Maximilian Turovsky,[16] Ilya Andrushkevich.

After the Soviet occupation, the Shepetivsky house of forced labor (hereinafter referred to as Izyaslavsky BUPR) and the Special Department of the Сheka were stationed in the monastery buildings.

The last Bernardine friar left the city in 1932, having previously organized the export to Poland of the archives and libraries of the monastery, as well as parts of the equipment.

St. Michael's Church is a one-nave temple on the Latin planning cross, at the expense of the transept, to which a square tower in the projection of the south adjoins.

To the west is a narthex, above which is an open gallery, adorned with wrought-iron lattices, fixed on brick columns, the entrance to which is located from the choirs.

The western façade is performed by a mannier[check spelling] pediment, decorated with volutes, pilasters and advanced eaves.

It included a breast wall with loopholes, preserved on the facade from the west, decorated with armature, pilasters and ornamental friezes.

The problem of protecting the architectural complex of the Bernardine monastery arose immediately after the former owners lost complete control over it and placed it in part of its premises at BUPR.

In particular, the following objects were protected: the part of the monastery that was used by the religious community (the building of the church of the beginning of the 17th century, the tower, closed adjoining corridors, the wall in front of the church, the house to the left of the entrance gate, the so-called palace chapel, the bell tower to the right of the entrance gate, the dome pavilion with the crucifix in front of it, the tombstone between the palace chapel and the church); part of the former monastery, which was adapted to the needs of Shepetivsky BUPR (all facade and interior walls, yards, corridors, cells, stairs, dining room (reception), annex near the courtyard corridor, wooden carved doors near all doors).

Instead, the BUPR administration, contrary to the Regulations on the Protection of Cultural and Nature Monuments, approved by the VUZVK and the RNA of the Ukrainian SSR on 10 June 1926, actively reorganized the premises and adapted them for their own needs.

The work was carried out by prisoners in violation of construction technology, «smoke from the chimneys penetrated went through the wooden floorboards into the corridors of the second floor».

[20] By resolution of the Council of Ministers of the USSR of 24 August 1963 № 970 a complex of monuments ("Bernardine church, cells, walls with gates and towers"), located in the territory of the Iziaslav prison, under № 760 was taken under the protection of the state.

[21][22] St. Michael's Church and Monastery of Bernardines is listed in the State Register of National Cultural Property (monuments of town planning and architecture), security numbers of the complex 760 0–760 3, which also includes "walls with gates and towers".

[27] Such memory of the formation of the logic of the Red Terror in the Bernardine monastery was left by the peasant P. Tymchyk from the village Dvirets: Slippery mold in the corners of the prison, cold and wild.

In particular, it was noted that in the Iziaslav camp in the last year there were recorded cases of images and beating of weak teenagers, confiscation of food, belongings, and money from them by the colony workers.

[34] Until 1958, the head of the supervisory service of the Iziaslav Children's Labor Colony of the Ministry of Internal Affairs in the Khmelnytsky region was Alexey Devyatov, one of the executors of mass shootings of Polish POWs in the Putivl camps in 1940.

Therefore, people were spiritually broken and began to cooperate with the administration, or seriously ill, and then did not cause any interest in the leadership.»[36] – recounts one of the former prisoners in Iziaslav.

» [43] Due to the horrific conditions of detention and cruel treatment of prisoners, the institution of the Ukrainian penitentiary system Castle Correctional Colony № 58 (names in the criminal world: Monastery, White Swan) is permanently mentioned in human rights and media discourses.

It is a question of working out of fighting skills by militia special units of the Ministry of Internal Affairs of Ukraine on persons serving sentences in prisons.
