In this guide there is neither the Hermitage nor Peterhof - the authors invite you to Leningrad. But Petersburg is also in this book, because it was he who determined the character of Leningrad modernism. Modernism here was not a rejection of tradition, but a reflection on its occasion. This is the modernism of traditionalism - not "militant," but dialogic - which is interesting. In the era of space and jazz, Leningrad architects continued to think in ensembles, and not in separate objects, which then seemed archaic, but it is this environmental approach that turns out to be the most modern today.
