Since the 1970s, researchers have studied various aspects of humanistic geography, including the sense of place and people's relationship to it. One of the most significant initiatives that help to transform cities into desirable locations for living, as well as a hub for interaction between people, built and natural environments in cities, is the development and beautification projects. The main goal of the study was to improve a theoretical framework to analyze the success of development and beautification projects in Sur city in enhancing the sense of place in the urban environment in the Sultanate of Oman. It, also, aims to analyze the tangible and intangible components of those projects. Moreover, it aims to analyze the effectiveness of development and beautification projects' role in enhancing the interaction in public places and people's behavior in these projects. Analytical descriptive approach was used to find and adopt suitable indicators to evaluate the sense of place. This analysis led to extracting 12 criteria to evaluate the effectiveness of the projects. In addition, this study relies on censuses, statistical publications, and Observation. The study used In-depth semi-guided interviews with 17 citizens and questionnaires that were distributed to 283 residents who frequently visit the development and beautification projects. The study's findings show that all projects had a high sense of place according to the mean values. In the three projects, place identity takes the highest value than place attachment and dependence indicators. However, the results of the three indicators showed that some criteria need to be developed and improved, such as the familiarity and vitality criteria, as well as some gaps in some aspects of planning for the urban fabric that surrounds these projects. This study also supported the idea that Sur's characteristics such as the natural environment and the history of maritime navigation د played crucial roles in identifying the place's functional, social, cultural, and emotional values. The study recommended that the functional components of these projects should be developed and revitalized. Furthermore, local participation processes and urban development and renewal projects should be activated beside the city's various social groups.
