The object of the research is developed around the historical gardens belonging to certain historical monuments, more precisely in relation to the palaces and manors of aristocratic families from the Banat area. These gardens are selected according to certain criteria that preserve physical and documentary stylistic and memorial values. The aim of the research is the studying of a frequently met phenomenon both as specialists in the field and as simple citizens, that is, the loss of values of a building and its surroundings, which at the time of their construction had a special historical and architectural value, but with the passing of time they lost some of these values due to political, social, and cultural changes.

This paper has the purpose of investigating these still existing landscape arrangements as well as the main factors that lead to their transformation, their problematics being discussed from its historical, architectural, and social-cultural perspective.
