Under the rule of Ivan III foriegn architecture began to appear in Russia. The first instance of this new type of aarchitecture was with the construction of Moscow's Assumption Cathedral in 1479. Foriegn architecture was also used in the construction of St. Petersburg under Peter the Great's rule. It is influenced by European design. Today Russian architecture has a more modest approach to it.
The popular "onion dome" first appeared on the Cathedral of Sancta Sophia in Novgorod. For a long time churches were the only buildings that were allowed to be made of stone.
