Maria Concordia mine
An underwater photogrammetry survey of a flooded magnesium mine located in Sobotka, Lower Silesia, Poland
What is Maria Concordia?
Maria Concordia, an old, flooded Magnesite mine with its irregular corridors, beautiful magnesite veins and crystal clear water seemed to be the perfect site to conduct the survey. Our goal is to create a complete photogrammetry scan of all 4 corridor levels, along with the 40m deep shaft.
Media and supporters
Both Maria Concordia Project and Submerged Foundation received worldwide recognition, resulting in fascinating sponsorships and media partnerships.
THE PROCESS
Scanning the whole mine was an endevour that required through planning and a multidisciplinary execution team
photographs
Collecting this amount of data requires thorough planning on all of the project stages. Each dive was carefully planned. The data collection was split into several days so the captured material could be evaluated in the meantime.
hours of processing
Diving is only the first step of the whole adventure The whole catured material needs to be processed in the photogrammetry software
hours under water
The total dive time includes not only the scanning itself, but also the time of support divers and the time spent on the documentary photoshoots by Michał Antoniuk
km scanned
We managed to scan all 4 flooded levels. Al together with all of the side corridors, excavation chamber etc it sums to over 3000m of photorealistic scan.
The outcomes
An underwater photogrammetry survey of a flooded magnesium mine located in Sobotka, Lower Silesia, Poland
Outcome #1
Cross sections
The great advantage of working with a 3d model is the possibility to quickly create a cross section along any axis, preserving the photorealistic details.
Outcome #2
PHOTOGRAMMETRY MAPS
Meticulous process of connenting the corridor chunks allowed the team to create a highly detailed maps of the first 2, largest levels.
Outcome #3
Virtual Dive Videos
Thanks to the virtual tour videos you can plan your dive well ahead. 360 videos are coming soon.
Documentary photoshoots
While capturing the beauty of the Concordia mine using the photogrammetry technique, we couldn’t forget about taking some stunning documentary photographs.

The maria concordia project showreel
The project of that scale is hard to describe briefly. So instead, take a look at this making-of video our team has prepared!
ADDITIONAL PUBLICATIONS
The project resulted in quite a few publications in world-wide media and talks on diving and speleology events all over the world.
THE MARIA CONCORDIA TEAM
The Maria Concordia Project would not be possible of not for the cooperation of some dedicated and skilled divers and photogrammetry experts.
