This research is aimed at understanding the regeneration process of the historic urban fabric in the Sultanate of Oman and identifying the key stakeholders engaged in this process. Through the case of Harat Al Aqr in Nizwa, this study was carried out to answer the question 1- What is the current status of regeneration in Harat Al Aqr? 2- What are the aspects that should be considered during the regeneration? 3- Who are the key stakeholders in this process? And finally, 4- What is the process of heritage regeneration of harat In Oman? In the effort of answering the research questions, 4 main objectives were planned to be achieved which are: 1- Documentation of the transformation of the urban fabric in Harat Al Aqr. 2- Identify the aspects to be considered in the regeneration process of the historic urban fabric in Oman.3- Identify the key stakeholders involved in the processes of regeneration of historic urban fabric in Oman. 4- Investigating the Process operational steps & stakeholders' involvement within the process. A mixed research methodology was implemented. It involved on-site surveys and observations, questionnaires, the Delphi method, and semi-structured interviews. The snowball and convenient sampling techniques were used to select the targeted interviewees among the different stakeholders. A set of 25 experts consisting of governmental officials, professionals in architecture, urban, and heritage fields, and some of the local community actors participated in 2 round interviews to determine the key stakeholders. The results from the research procedure, particularly from the interviews and through the Delphi method supplemented the system, created from the other literature reviews on the same topic of study. The outcomes obtained all throughout the research process assisted us to understand more about the stakeholders' engagement in the process of urban heritage regeneration in Oman. It is concluded that heritage development in Oman requires more interaction between involved parties and further inclusion of stakeholders who currently have limited roles. There is also a need to develop a well-structured rehabilitation process. And finally, the integration of local community actions within the decision-making stage and the process steps of heritage regeneration is a key factor in the success of any operation of urban regeneration. The limitations and implications of this research include but are not limited to: the difficulty in finding experienced people in heritage fabric regeneration. Lack of literature within the Middle East context especially in Oman. Limited knowledge among the stakeholders concerning the issue of traditional Harat regeneration, since this kind of development, is just currently raising in Oman.
