Acta Scientiarum Polonorum

Following the statistics maintained by the National Heritage Board of Poland dated 31 March 2014 currently
183 192 monuments have been listed at the territory of Poland. According to the list delivered in
2016 by the Provincial (Opole Province) Monument Conservator, 40 of them are threatened by a construction
catastrophe. Some of them require an immediate construction intervention. The statistics show
sobering figures but due to a various ownership status and financial situation of the owners unfortunately
repairs are not carried out on a regular basis. On the basis of the geological and construction documentation
it has been examined the settlement of one of the sacral monuments in Opole Province that was formed
throughout centuries. The stage I has covered the analysis of the behaviour of the original foundation of
a church settled on a slope. The stage II has embraced the analysis of the foundation that was strengthened
and the slope that was secured by a brick retaining wall. The last III stage of calculations has been devoted
to the foundations of the structure after being reinforced and the retaining wall strengthened by concrete
reinforced coating and a palisade of micropiles anchored to the wall. The main focus has been put on limit
equilibrium methods. On the basis of the results the slope and structure stability has been estimated. As to
preserve the historic building for future generations the direction of further conservatory works has been
determined.
