What does an archaeologist see when walking through the Summer Garden or Peterhof? The mistakes of restorers who sometimes overlook what is in plain sight. Viktor Korentsvit will talk about the omissions and oddities noticed in iconic architectural ensembles. But - without criticism, with irony and love for the city. The Summer Garden, Peterhof, Oranienbaum, Tsarskoye Selo - pearls of architectural heritage that St. Petersburg is proud of. But what if we look at them through the eyes of a professional who knows their history in minute detail? Viktor Korentsvit - an archaeologist, restorer, and one of the leading specialists in the archaeology of St. Petersburg - invites you to a lecture where he speaks not about magnificence, but about mistakes. These "annoying mistakes" are sometimes noticeable to everyone - crooked elements, inappropriate materials, stylistic distortions. But it is the specialist who can explain why they are important. And most importantly - to do this not dryly and formally, but vividly, with a touch of irony and genuine care for the city. Viktor Abramovich calls himself a "benevolent tourist" - because his goal is not criticism, but conversation. About how to preserve the spirit of the time, how not to lose the historical face, and why restoration is not only about technique but also about ethics. The lecture is suitable for everyone who loves St. Petersburg and its suburbs, who cares about the urban environment and how it changes. It will be interesting for those who are engaged in architecture, history, restoration - and simply for those who notice details and ask questions. After this meeting, walks in your favorite places will definitely become a little more attentive: you will start to see what previously eluded you. This is not a strict academic lecture, but a lively communication with a person who truly loves the city. Viktor Korentsvit shares not just observations, but a perspective that combines experience, depth, and genuine St. Petersburg respect for the past.
