Abstract
Engineering-geological and geo-ecological conditions of the territory of the architectural and historical complex of the Peter and Paul Fortress located on Hare Island have been analyzed. Historical and ecological analysis of the peculiarities of the development of the territory of the fortress, including the construction and operation of the Peter and Paul Cathedral was carried out. The main pollutants of the underground space of the island that have a negative influence on the condition and properties of the sandy-clay soil at the base of the cathedral, underground water and construction materials have been singled out. Calculation of Stability of the Peter and Paul Cathedral was carried out. It is shown that the development of long-term and uneven settlements of the cathedral is caused by the transformation of soils at its base and the destruction of the foundation. The organization of the object monitoring system of the Peter and Paul Cathedral is proposed.
