At 95 meters in height and 79 meters in length, the Military Cathedral is one of the largest Orthodox churches in Russia. The. Saviour-Not-Made-by-Hands icon that looks down from the central dome is the largest image of Christ’s face ever created in mosaic. Clearly, the church was built with the intention that it would stand alongside St. Basil’s and other important Orthodox cathedrals as a significant Russian landmark.
