Environmental impacts on historical buildings – an example of the bridge over the former "Głęboka Droga" in Puławy

The destruction of historical buildings most often results from the physical wear that may occur over time, as well as wear of functional (utility) and environmental nature. Environmental wear of the monuments is related to the changes in the vicinity of a facility, which causes a nuisance in operation and adverse ecological changes. Environmental factors affecting the building structures can be divided into three basic groups: external threats to the environment (neighborhood nuisance), random threats and internal environmental threats. The article presents environmental factors affecting the condition of the historical bridge in the palace and park complex of Princess Izabela Czartoryska in Puławy.
