Information about the object:
The Church of the Nativity of Saint John the Baptist in Mosciska belongs to the oldest parish in Przemyśl. The parish belonged to this diocese until 1991. It was founded in 1404 and endowed by Władysław Jagiełło. The temple received its present shape at the end of the 16th century. The painting decoration by Julian Kruczewski, created in 1902, decorates the whole interior of the temple.

2020
The project was a continuation of conservation work on the 17th-century illusionist polychromies in the Chapel of Our Lady of Czestochowa in the Church of the Nativity of St John the Baptist in Mościski (Lviv Province).

The aim of the project was to save the object, improve its state of preservation and create the right conditions for its effective protection. The problems with the soggy plasterwork in the chapel and the uncovered paintings made it necessary to urgently undertake extensive conservation and restoration measures and to restore the frescoes and plasterwork to proper technical functioning conditions and optimal aesthetic qualities. The manner and method of their conservation depended on the results of the research carried out and on the tests carried out on the object.

In the current stage, technical and aesthetic conservation was completed on the vault and part of the walls, as well as the reconstruction and arrangement of the fragments of paintings that had not been preserved. All conservation work was properly documented. The work was carried out by an international team of conservators and conservation students from the Academies of Fine Arts in Kraków and Lviv. The project enabled an exchange of experience and promotion of the Polish school of conservation.

2021
The project consisted in the continuation of conservation work in the Chapel of Our Lady of Czestochowa in the Church of the Nativity of St John the Baptist in Mościski. During probing of the 17th century chapel, illusionist wall paintings were discovered. They cover the walls and the vault of the chapel. They were located under several layers of whitewash. The poor condition of the object (soggy and mouldy walls in the lower parts) meant that conservation intervention was urgently needed. Their main aim was to restore the paintings and plasterwork to proper technical functioning conditions and optimum aesthetic qualities. Their conservation methods were chosen on the basis of the results of the research carried out.

The conservation process of the chapel, thanks to funding from the Ministry of Culture and National Heritage, has been ongoing since 2018. This year, the aesthetic conservation and reconstruction of the missing elements of the painting decoration on two walls of the chapel, the eastern and western walls, was completed. The cement patches were replaced with wide-pore lime-sand plaster.

Funding: Programme of the Minister of Culture and National Heritage "Protection of Cultural Heritage Abroad".
