The city is no longer observed – it is experienced.
Imagine: Tourists scan a QR code at Lindenhof and suddenly find themselves face to face with Johanna Spyri, who personally tells them about her life and "Heidi." At the Grossmünster, Huldrych Zwingli appears and explains the Reformation.
Eternal Echo transforms historical sites into vibrant encounters with the people who shaped those places.
