6. CONCLUSIONS 
An edifice of such quality and importance like the KAM needs 
all efforts to save and guarantee its function and existence. On 
the one hand risk for the building or at least for same parts of 
the dome are existing at present day. The necessary restoration 
works are in stagnation, it may be caused by the necessary and 
also missing money but more by being afraid of the 
consequences of possibly unprofessional or risky decisions. On 
the other hand we must realize that the edifice especially the 
octagonal centre with the dome, exists for 1500 years because 
of the very high robustness of the structure. But now the 
disregarding of the existing dynamic effects in some parts of the 
dome may be the wrong decision of dealing with. One of the 
scientific answers must be to collect and distribute all existing 
information of KAM, the old idea of a complete and usable 
building information system must be recalled.
