    Modern Digitization and 3D Visualization Technologies for Virtual Access to Hard-to-reach or Perished Historical Sites

    Nowadays, an important issue is both the digitization of Cultural Heritage objects and the techniques of their virtual dissemination, regardless of the current state of the digitized object. This is crucial when the digitized location is at risk of closing, degradation, or complete loss due to natural disasters, armed conflicts, or political and economic conditions. Obtaining a digital twin of such an object allows not only to maintain the most accurate representation possible but also to implement an unlimited number of sessions to disseminate such an object, regardless of whether the object is only difficult to access or has already been excluded from display, damaged, or even completely lost. The paper presents detailed case studies of 3D scanning and model sharing for inner chambers of the Golden Mosque in Samarkand (Uzbekistan), the Church of the Archangel Michael in Chicago (USA), and the Church of St. Adalbert in Chicago (USA). The acquired data is based on TLS scans and photographs of the interior. The point clouds and mesh models generated from them provide a density adequate to the detail of the interior appearance and geometry. The Golden Mosque is a part of the Tillia-Kori madrasa (dating from the 17th century) located in the Registan complex in Samarkand, Uzbekistan - located in Central Asia. In turn, the Church of the Archangel Michael in Chicago (built in 1909 by the Polish diaspora) was desacralized in 2020 and closed. Its digitally documented condition shows the abandonment of the building that served the congregation until the very last moment. The demolition process of the Church of St. Adalbert in Chicago began in 2023. At the beginning of this process, it was possible to carry out a 3D scan of its interior and separately of the Pietà sculpture (a copy of Michelangelo's Madonna della Pietà) already transferred to another church. All of the above results are publicly available in the form of basic and online 3D models, panoramas, videos, and VR files.
