The architectural object is a witness of its age. Its form is the result of once existing requirements and fulfilling defined needs. Over time, however, conditioning is changing, repeated destructions and transformations causing that a historic building stops responding to original assumptions. In consequence a need of assigning a new role to monuments appears: a purely museum-like relic or a fully functioning architectural space adapted to modern expectations. It seems that in spite of functioning regulations, undertakings effected in the last decades depict a different level of taking a stance on the authenticity residing in a historic structure. Perhaps there is a need to take another look at the model of conservator’s action adequate for redefining the position in view of the protection of historic values, withthe possibility of considering additional decisions, towards specific objects and circumstances.
