Three central squares of St. Petersburg – Palace Square, Senate Square and St.Isaak's Square – with the Winter Palace, the General staff building, the Admiralty, St. Isaac's Cathedral  located on them and other buildings form a uniform spatial organism on the bank of Neva. 

The ensemble of central squares was created and got the modern look in a result of successive creative activity of several generations of Russian architects. The most responsible task in formation of ensemble of three squares fell to the lot of A. D. Zakharov who created one of the greatest architectural works of the world - the building of the Admiralty serving as a connecting link between Palace Square and Decembrists Square.

The Winter Palace, the Admiralty, St. Isaac's Cathedral, the Senate and the Synod are turned by their northern facades towards Neva. Its broad water spaces are inseparably linked with prospects of the grandiose squares and powerful massifs of the buildings located on them. Exactly here greatness and a unique originality of architectural panoramas of the city reveals to those who are in love with St. Petersburg with a special force and clarity .
