The authors conducted fundamental philosophical research. Issues of history, philosophy and theory of ancient Russian architecture are interpreted as integral to the question of the very essence of the emergence of the phenomenon of Holy Russia. This is a serious and multifaceted study not only in the field of architecture, but also the spiritual essence of history and culture. This book can encourage modern architects designing in historical cities to rethink their architectural creations and help them absorb traditional forms of the creative method in order to follow in the footsteps of historical memory with their works and not harm the ancient spirit of the “city-home.” The book is a reminder to compatriots of the original essence of our common “home” - the image of the house, the house-city, the city-Rus. Trinity - past, present and future.
