In the past the chief building materials preferred by Russian architects were wood and clay. As confirmed by historians, bricks made of clay, date back in Russian history to the 10th century and before this, timber was used as the main building material since the beginning of time… Wooden architecture became a base of the Russian middle age architectural movement, which was characterised as an ideal combination for its beauty and usability…

This architecture is still admired today.
One wonders how they used to build in the past without the use of nails and screws. The basic tool of medieval building was the axe.
