In recent years, art museums have expanded their role as cultural education institutions, responding to social demand for lifelong learning and transforming from exhibition spaces into professional educational organizations. This study examines children’s programs conducted at the An Sang-cheol Museum of Art in northern Gyeonggi Province in 2023 and 2024 to explore ways of strengthening cultural accessibility in local communities. Initially a one-time activity, the program developed into a long-term initiative and was institutionalized through MOUs with nearby elementary schools, showing how an educational model can achieve social expansion. Designed to enhance accessibility for local students, it offered art appreciation and practice guided by professional museum staff. Provided free of charge, the program positioned the museum as a “neighborhood art museum,” lowering psychological barriers and encouraging residents to move from potential users to regular visitors. By presenting this case, the study proposes sustainable approaches to children’s art education and practical measures to improve cultural accessibility.
