The permanent Structural Health Monitoring (SHM) system applied on the historical man made Kosciuszko Mound in Cracow is presented in this paper. A limited data gathering system applied after the revitalization of the mound in 2012 is described at the beginning, followed by the description of the comprehensive monitoring system which was introduced after 2014. It is shown, how the data on relative displacements and deformation of individual layers in the internal structure of the mound are obtained and constantly updated and how this type of information is associated with the corresponding meteorological data. At the same time the observed trends in changes as well as the correlations between individual parameters resulting from climate changes usually following the yearly cycle are indicated. Based on this background a novel data management system is proposed supported by alternative decision strategies. In the first of the compared strategies relatively infrequent actions are preferred, at the high risk of failure with potentially serious consequences, and thus relatively costly, while in the second strategy small scale interventions are preferred, initiated more frequently, but at much lower risk level.
