However, a monument that is beyond this list istheŽebračka Mine—a local sinkhole located in the Moravian-Silesian Region in the cadastral area of the municipality ofHeřmanovice, but historically belonging to Zlaté Hory. It is not an old monument, but since it is a local sinkhole, it is changingas a result of weathering when the rock falls from the overhang and the side of the mine. Since 2013, the mine has been monitoredby 3D laser scanning, and since 2003 by seismological monitoring. This monitoring proves that it is still a living monument. Thestudy evaluates a unique data series of registered seismic events related to the effect of the rockfalls covering the period of 16years. The mutual confrontation of seismological data with atmospheric conditions, namely, outside air temperatures andprecipitation, enabled to reveal the long-term development of the rockfall activity and to determine the influence of specificatmospheric parameters. The results show that the most extensive rockfall activity occurs at temperatures oscillating around thefreezing point and is thus primarily related to the freezing and thawing of water in fissures of weathered parts of the rock mass.Understanding these processes is essential for forecasting the possible development of the sinkhole in the coming decades and forall other planned activities at the site related to its opening to tourists. In addition, the knowledge gained from the research willprovide valuable information for educational purposes for visitors to the site, to understand the weathering processes taking placethere, and to understand the behaviour of the geological environment in the given climatic conditions. Moreover, visitors willlearn about current methods of monitoring the stability of the rock mass in situ. The planned opening of the sinkhole to touristswill be reflected in the increasing attractiveness of the region and will attract many enthusiasts in the field of mining history andgeology, not only from the Czech Republic but also from nearby Poland.
