The modernization of Islamic countries has brought significant changes to heritage buildings, particularly in construction and architecture. The Bazaar, as one of the most important heritage buildings, has played a crucial role in shaping people's identity, culture, and political, economic, and social characteristics. However, the development of new trade centers and the city's expansion after the Industrial Revolution caused a shift in the Bazaar's functions, resulting in its loss of values and social roles in the lives of new generations. To preserve heritage buildings for future generations, cultural sustainability approaches have been considered, and adaptive reuse models are being used worldwide. This study focuses on historical typology in Tabriz, Iran, and uses adaptive reuse models (ARMs) to evaluate the Tabriz Ground Bazaar based on cultural sustainability. The study aims to achieve the potential of rehabilitation by utilizing the SWOT analysis. The selection of Tabriz Ground Bazaar as the case study was based on the quantitative research methodology.
