This study aims to analyze Maimun Palace as a cultural heritage site and educational tourism destination in Medan City, focusing on its historical and cultural value, its role in preserving the Malay Deli cultural heritage, and its function and contribution to educational tourism. A descriptive qualitative approach was employed. Primary data were obtained through interviews with T. Nuhzatul Syima Delikhan (Tengku Puteri Seri Kemala)—a key informant from the Deli Sultanate family—and Dayana Sabila, a visitor and university student. Secondary data were derived from legal documents, official cultural and tourism sources, books, and scholarly articles. The results indicate that Maimun Palace possesses significant historical and cultural value as a legacy of the Deli Sultanate and a designated national cultural heritage site (under Decree No. PM.01/PW.007/MKP/2010). These values encompass the history of the Deli Sultanate, Malay Deli identity, an architectural blend of Malay, Islamic, Indian, and European styles, and the cultural memory passed down to the community. Maimun Palace plays a role in preserving Malay Deli cultural heritage through the maintenance of its buildings, collections, and traditions, while also serving as a symbol of cultural identity for the people of Medan. However, preservation efforts face challenges regarding internal issues, the need for building and infrastructure maintenance, and the need to strengthen government cooperation. As an educational tourism site, Maimun Palace contributes to enhancing public and tourist knowledge regarding Malay Deli history and culture through visits by tourists, school groups, and cultural activities. Nevertheless, the dissemination of historical information needs to be strengthened through guided tours and interpretive media to optimize its educational function. The study recommends strengthening educational tourism, improving area management, fostering institutional collaboration, ensuring sustainable
