ABSTRACT
In the area of Prague Castle there is already about 10 years of periodical measurement of the height and positional changes in the buildings and structures being performed. This paper is focused on the positional part, the measurement was carried out with use of precisely measured polygons. Until now, these measurements have been evaluated only locally with respect to each building and its stability without an overall view of the situation of possible movements of individual parts of the surface of Prague Castle. Whereas there are height shift of some points between epochs undoubtedly, a new and complete adjustment of each measured epoch and mutual assessment of changes between epochs using robust analysis of the linear 2D transformation between epochs was conducted. This comparison shows the relative movement of certain parts against another. The results are consistent with current knowledge of the geology in the area of the Prague Castle.
