Review article

The article considers the development of the architectural and structural system of buildings in St. Petersburg during the reign of the Empress Anna Ioannovna. During this period, there were worked out space-planning and design solutions, which were successfully and almost invariably used throughout the XVIII - XIX centuries. Vaulted passageways in the main street buildings leading to the inner courtyard, rafter roof structures over cold not heated attics, unique designs of spires and tiered completions of temples - these are some of the constructive developments of this era. Generalizing the experience of the structures` development allows appreciating the evolution of construction skills, identifying and preserving the historical structural elements of the buildings of the city center.
