How are ancient Russian cities similar and different from European ones?

They differ in style of structure, atmosphere and way of life. In addition, it should be noted that Russian cities were cleaner than European ones. There are differences in architecture, which is largely due to the difference in natural and climatic conditions. So in Europe, a milder and warmer climate, hilly and flat areas, there are no swamps. In addition, ordinary urban buildings in Europe very quickly began to be erected from stone, while at the same time Russian cities were mostly made of wood.
