Security works are of great importance in the field of protection and preservation of architectural monuments. They are like an intermediate link in the field of technical intervention, which removes the state of danger caused by one or other reasons and affects the extension of the durability of the monument.

Timely and appropriate security measures have a positive effect on the state of preservation of the monument, they prevent the development of destructive processes and create more favorable conditions for the proper conservation action, especially they have a decisive influence on the scope of works in the future and limiting the amount of incurred financial outlays.

Various issues may occur in the process of securing monuments. In terms of technical issues, security works can be subordinated to three main directions, which include:

a. Construction prevention security, and therefore related to the use of all kinds of measures to prevent the object from being damaged by rainfall and lightning - fires, moisture, the actions of parasites, mushrooms etc.. - preventing mechanical and chemical damage to these building elements, which are not of a structural nature, and are related to its external and internal design or the comfort of use.

b. Security related to static and endurance prophylaxis, which also includes all work on the temporary strengthening of the structural organism and its individual links. In this case, the scope and nature of the protective works results from the maintenance of the technical condition of the structure and the degree of threat.

c. Securing the area, with which the monument is permanently connected, and whose breach or neglect causes serious consequences for the monument. In this respect, the main task will be to prevent the effects of motion and ground vibrations, disturbing the balance of earth masses, turbulent water effects, expansion of vegetation et al.

The effectiveness of works related to the protection of monuments is closely related to systematic, periodic inspections of the state of preservation of buildings and timely detection of dangerous destruction centers.

In terms of technology, the security may be temporary (preventive) or permanent (stable). In both cases, the measures applied are closely related to the program intended for the protection of the monument.

In conservation practice there are various ways and methods of preventive and permanent protection, the more complicated these issues are, the more damaged the object we deal with.
