The history of Sergievka connects imperial gifts, family legends, and a landscape park with a mysterious stone Head. In the lecture, the palace, ponds, and the fates of the estate's owners come to life - from the times of Nicholas I to the research center. It is a story about a place where nature and memory work as a whole, prompting a new perspective on familiar routes. It is hard to imagine St. Petersburg without its suburban residences, each with its own intonation. Sergievka on the Peterhof road is not the imperial facade, but a half-hidden story of family ties, scientific centers, and the slow passage of time among old trees. The lecture helps to see behind the lines of guidebooks a living place where the fates of people and the fate of the landscape intersect. Listeners begin their journey with the first owners of these lands in the 18th century. One by one, owners, tastes, and fashions change, along with the country house becoming more complex, with ponds, paths, and pavilions appearing. Special emphasis is placed on the moment when Nicholas I gifts the estate to his daughter Maria Nikolaevna for her wedding to Maximilian Leichtenberg. Through family stories, letters, and memories, it becomes clearer how the aristocratic family lived away from the ceremonial halls of the capital. An important part of the story is dedicated to the palace of architect A. I. Stakenschneider and the landscape park around it. The audience will learn why the mysterious stone Head appeared here, how the old ponds are arranged, and which routes were popular among the owners and their guests. Architectural details and the layout of the estate are examined not dryly, but as a backdrop to everyday life, walks, conversations, and family rituals. A separate plot is the 20th century. Revolution, change of power, the transfer of the palace and park to biological scientists, and the emergence of a scientific institute give the place a new sound. Through the example of one estate, it is visible how the attitude towards private heritage has changed, what has been preserved, and what has been irretrievably lost. The lecturer shows that the current state of Sergievka is not a coincidence, but the result of a long chain of decisions.
