In 2024, an innovative application was created at the initiative of the Holy Trinity Sergius Lavra.
It allows users to explore Andrei Rublev's masterpiece, the "Holy Trinity" icon, through augmented reality (AR) technology. This app provides a unique opportunity for an AR tour, unveiling the secrets and symbolism of Rublev's famous work. Using a smartphone camera, users can focus on the icon's image and gradually study each element, gaining a deeper understanding of its spiritual and artistic significance. The AR technology enables a virtual presentation of monastery exhibits, discussing theological depth and iconographic symbolism, highlighting Andrei Rublev's contribution to iconography. The app is available for download on RuStore, AppStore, and Google Play.
