Rezumat/Abstract. This paper aims to present a view based on specialized literature and personal observations regarding the concept of heritage in the context of the current requirements of transforming cities into sustainable urban entities. The paper presents ways of integrating the medieval city of Sighisoara into this general trend. The development of the concepts of heritage and sustainability through the prism of specialized literature was preferred and the study comes with viable proposals of rethinking the medieval fortress of Sighisoara by highlighting successful policies implemented in several similar European cities. The main objective was to carry out an initial applicability study in Sighisoara concerning the methods and techniques used in the still inhabited medieval cities. This transformation should be thought of without affecting the heritage value. The study of techniques and methods applied at European level in cities with a similar history was also considered. For this purpose, on-site observations were necessary both in Sighisoara and in other cities that are the subject of comparative surveys, as well as discussions with local competent bodies. The results obtained led to conclusions, both regarding the measures required to be immediately applied, and the sustainable future evolution of the city of Sighisoara.
