Thank you Svetabel. I do not speak Russian, but it sure seemed they were taking an almost archeological interest in the interior, especially in regards to the brick work and their markings.
It seemed like some work was going on or at least had been going on. Do you know if there has been any restoration work? Is there an interest to display or use the building in any way? I saw the video was made in 2010 and the interior was in a frighteful condition.
