Everything that had been built has a duration period. Construction is deteriorating, function is changing and shape become questionable. Historic buildings and environments had own logic of building it up. Those buildings if protected as a historic monuments are raising many questions and disputes. Changed circumstances in technology and materials, new kind of function and an idea of contemporary rationality are often in confrontation with a past and dead image. Ruined remains might be easily be obstacles for reasonable behave in space, or frozen existing reality might protect a normal life development. Sometimes with kunsthistorics it seems as the end of history has come.
