What is particularly striking about the cathedral is its asymmetrical architecture, which greatly distinguishes it from most other Russian Orthodox church buildings. The central element of the house are its nine church towers with brightly painted onion-shaped domes, some of which are very different in size and colour. The latter also has the effect that the building does not have a main facade and therefore offers the viewer an unusual view from every side. Originally built of white stone, the cathedral was decorated in places with red bricks during a renovation in the middle of the 17th century, which gives it its striking colour heterogeneity to this day. The inside of the cathedral is also very imposing with a labyrinth-like system of corridors and galleries.
