This article presents Quintana Quest, a browser-based visual novel developed as part of the interdisciplinary educational project “Abenteuer Donaulimes,” aimed at making the largely invisible Danube Limes World Heritage Site in Bavaria accessible to young learners. Designed for students aged 10–12, the game combines storytelling, historical accuracy, and interactive gameplay to foster engagement with Roman frontier history. By embedding real archaeological sites, museum artifacts, and historically informed characters into a narrative-driven format, Quintana Quest offers a compelling example of game-based learning in heritage education. The project links digital exploration with museum visits, providing teachers with curriculum-aligned materials and promoting meaningful interaction with cultural heritage. This case study illustrates how digital tools can bridge gaps in visibility, understanding, and emotional connection in the interpretation of World Heritage.
