The use of augmented reality and GPS-guided applications has proven successful for reviving cultural heritage. However, the impact of using these technologies on the learning process of cultural heritage has not been studied in depth. This article reports the findings of how using GPS and augmented reality with mobile apps impacted learning during a project to reactivate cultural heritage around Medellin's Cisnero Square and its surroundings (also called the "Park of Lights"). An experimental test comparing two groups was performed. The experimental design goal was to determine the differences in learning and user perception when the proposed Mobile App was and was not used in guiding the cultural heritage tour as part of Cisnero Square's reactivation. The results showed that the experimental group achieved better learning and cultural heritage learning outcomes. This study offers valuable insights into technological applications for reactivating cultural heritage, which can be applied almost anywhere. © 2021
