The Mekong Delta is famous for ecotourism, with images of fruit orchards, vast fields, and a vibrant waterway transportation system. That iconic image is based on the development of agriculture, which resulted from fertile soil conditions created by an extensive system of rivers and canals. In the new urban development vision, the city authority considers riverside characteristics unique and need to be preserved and promoted as a basis for local socio-economic development, including tourism activities. The paper aims to research the value of indigenous landscape architecture in promoting urban cultural tourism through the case of the riverside area of Vinh Long City. Based on an extensive literature review and empirical works, this research examines the Vinh Long City waterfront better to understand the significance of architectural value in urban tourism. In addition, information from interviews with different stakeholders relating to heritage operations and tourism is used as qualitative data. Finally, the research design scenarios show the interdisciplinary vision for improving the riverine city identity. The article argues that riverfront landscape architecture can be a foundation for diversifying cultural activities in the city and further developing cultural tourism, complementing the current ecotourism strategy and contributing to a sustainable tourism strategy in the context of the Vietnamese Mekong Delta.
