Heritage being an inheritance from the past that is transmitted successively from one generation to the other plays a significant role in molding the memory of a country and forging its identity. As an element of heritage, architectural products are an expression of the cultural identity of communities. However, modern developments in historical regions ignore the presence of heritage buildings. Furthermore, the unorganized expansion of those areas led to the formation of leftover spaces. Abu Ali river is a historical region located in the city of Tripoli in Lebanon. Not long ago, this zone was considered the beating heart of the city before becoming a neglected area suffering from different social, economic, and environmental issues. One of the major problems the zone is currently facing is the loss of its cultural identity. In addition, the lack of green public spaces is noted. This paper attempts to revive the cultural heritage identity of Abu-Ali River area through the application of a cultural park using leftover spaces generated in the region as a site. The paper starts with presenting the theoretical background related to the topic; Then related cases are compared to reach the optimum project elements; Next the selected area is analyzed through macro-analysis, community analysis, and micro-analysis to reach initial design decisions; Finally, the application is designed based on specific social and environmental simulation tools. The application is expected to breathe new life into the neglected historical area and revive its heritage.
