The present research focuses on buildings’ names and commercial signs analysis as an important component of Bucharest city center semiotics in relation to place identity. Insufficient studies have focused on the direct relationship between commercial signs and place identity, and no scientific approaches in this sense have been identified at Bucharest level. The buildings’ names and commercial signs used as case studies are from the second part of the 19th century until the present. The profound economic and social changes that have taken place in Bucharest during more than 150 years are reflected in the findings. Relying on a complex methodology, a typology framing the case studies identified in the field highlights situations that are not necessarily in accord with the passage of time, but rather with certain city planning decisions and in relation to space use. The novelty of this paper lies in the investigation of some components of Bucharest city center that tend to be forgotten, providing in the end information in relation to their degree of appreciation and therefore preservation, or on the contrary, abandonment and loss. In this complex approach, the role of territorial actors involved in actions such as inventory, framing, and finding preservation solutions is discussed.
