Geolocated audio guides deliver an focused narration as you approach the Arco di Costantino, highlighting its role as a 4th‑century triumphal arch and the reuse of sculptural panels. In Discovery Mode, audio triggers at vantage points so you hear scale, relief details and its setting between the Palatine and Caelian. Tour Mode offers thematic chapters on imperial imagery, while gamification grants points and digital souvenirs for attentive listening.
