The book plunges us headlong into the atmosphere of post-revolutionary Leningrad - a city striving for a happy communist future. New times require new thinking and new art, and the old, obsolete art is being replaced by a vigorous and energetic avant-garde. In architecture, Art Nouveau is replaced by functional, restrained constructivism. There are many buildings in the city built in this spirit. It is they who are the focus of the author's attention. Before our eyes, history comes to life! The country is building new residential buildings, dormitories, schools, and hospitals. Houses of culture, department stores are being built, gardens and parks are being laid out - everything that a person of the future cannot live without. Everything is functional! Nothing extra! And even though now this style seems soulless and straightforward, it was the embodiment of the dream of a new society, and the fact that the dream remained a utopia is not his fault... Illustrated with old and modern photographs, the book will be of interest to everyone who is interested in architecture, to everyone who wants to know the living history of the Northern capital.
