Among the many activities carried out for the protection of monuments, geodetic measurements are primarily used for the inventory of objects and the study of their movements and deformations. In Jaroslaw at the Benedictine Abbey, the framework of the Scientific Association of Surveyors AGH, systematic surveying measurements of the walls and the verticality of towers of the church have been conducted since 2006. Thanks to years of measurements, the researchers were able to determine the movements of church towers and prevent their further swinging movements. In the paper, the authors show the course of the study and analyze the results. The surveying sampling was the basis for applying for EU aid which after the meeting the relevant requirements has been awarded in the amount of EUR 1.25 million to save the object.
