For the first time in its centuries-long history, the Kirillo-Belozersky Monastery, the largest monastery complex in Europe, is undergoing comprehensive 3D laser scanning using the latest geospatial technologies. The project, led by faculty and students from the Moscow State University of Geodesy and Cartography (MIIGAiK), aims to preserve and digitally archive the site’s architectural and spiritual heritage.

As reported by TASS, the digitization effort has officially begun this month. The first phase focuses on the monastery’s most sacred landmarks — the Assumption Cathedral and the Chapel of St. Cyril of Belozersk.

According to Mikhail Sharomazov, General Director of the Kirillo-Belozersky Museum-Reserve, the initiative is a multi-year collaboration with MIIGAiK, integrating both Russian and international scanning technologies. The university team, under the direction of Karina Khachatryan, Dean of the Faculty of Architecture and Urban Planning, has already conducted aerial laser scanning of the entire monastery grounds using the Geoscan-401 drone.

“These scans will allow us to generate highly detailed orthophotos and 3D terrain models,” Khachatryan explained. “The goal is not just to digitize the monuments, but to contribute to their long-term preservation, restoration, and scholarly study.”

Andrey Kupriyanov, head of MIIGAiK’s Department of Applied Geodesy, emphasized the cutting-edge nature of the project. “We’re using a full suite of tools — drones, satellite systems, and next-gen laser scanners — to record the structures with millimeter-level precision.”

Alexey Smirnov, Deputy Director of the museum-reserve, added that the resulting data will serve as a foundation for virtual exhibitions, multimedia experiences, and future scientific research. Plans are underway to create a comprehensive geoinformation system (GIS) of the entire monastic complex, enabling real-time monitoring of monument conditions and structural changes over time.

In addition to major architectural structures, specialists will digitize hard-to-reach features such as decorative tiles atop the Vologda Tower, icons on the Kazan Tower, and artwork in the Church of the Transfiguration.

The laser systems used in this initiative — recently acquired by MIIGAiK — were tested for the first time on the monastery grounds. These technologies allow for the creation of hyper-accurate 3D models, preserving the monastery’s historical integrity for future generations and opening new possibilities in conservation and education.
