Abstract

Paper concerns a construction disaster, which took place on June 4, 2018 in the 14th century St. George church in Hajduki Nyskie (Opole Voivodeship). The object is famous for its well-preserved 15th century wall polychromes. During the construction works, the eastern gable wall, part of the barrel vault with lunettes and part of the orchid roof truss collapsed at the roof truss. Some elements of the equipment were also destroyed. As a result of the catastrophe, valuable wall polychromes were directly threatened. Paper presents the causes and consequences of the catastrophe.
