The "Stone Head" (also known as "The Old Man" or "Adam s Head") which is Sergievka Park s most famous and mysterious landmark. Carved from a massive granite boulder in situ, its origins are unclear. Most researchers date it to around 1800, attributing it to an unknown master, possibly based on a design by Franz Brouer. The sculpture appears to be sinking into the earth, with its eyes wide open, gazing up from the bottom of a ravine near the manor house, surrounded by fallen autumn leaves. Sergievka Park, Old Peterhof, west from Saint Petersburg, Russia, October 13, 2025
Close-up of the "Adam s Head" (or "The Old Man") revealing the intricate craftsmanship carved directly into the granite boulder, highlighting its weathered texture and mysterious expression. The close view emphasizes the deeply carved eyes with distinct eyelids and pupils, gazing upward in a look of eternal surprise or contemplation. The nose is prominent and well-defined. The sculpture s rough granite surface is speckled with wet, yellow maple leaves, which contrast with the dark grey stone and emphasize its seamless, "sunken" placement within the forest floor.
