Thanks to non-destructive testing (NDT), it is possible to test the objects of historic significance and thus build up a clearer picture of their current condition. For the purposes of recovery these data are invaluable. Dynamic examination, static examination, technical diagnosis based on the NDT results and NDT monitoring of the structure of an object can determine all necessary parameters on the object, which is crucial for more reliable and safer design of the recovery. NDT monitoring enables continuous supervision of the structure; it can start before the recovery, take place during and after the recovery and has been carried out within the framework of controlling of the performed work.
Dynamic characteristics of the structure provide the information on the real condition of an object in the phase of exploitation. They can be experimentally measured by recording the response of the structure to the specific excitation, such as, in this case, road traffic, air traffic, influences of wind and music festivals. With the aim to tackle these issues, it is necessary to undertake the activities in recording of the influence of vibrations caused by named excitation of the load-bearing walls morphology and of the foundation morphology using NDT methods (it is common to use MT, UT, georadar etc.). Information provided, based on the results of testing, are necessary for this very complex problem. Many experts involved, such as archeologists, restoration teams, art historians, architects and construction workers had starting perspective often different, but with joint activities and NDT results they reach the same goal and that is the safety of the structure and preservation of a centuries-old building.
