The Beloozersky Kremlin is an earthen and wooden defensive structure in the historical part of Belozersk, which is now the district center of the Vologda region.

The earthen rampart and moat, which have been well preserved to this day, were built in the 15th century during the reign of Grand Prince Ivan III. Atop the thirty-meter rampart stood wooden walls and towers that lasted until the end of the 18th century, when they were dismantled due to decay.

Until the mid-14th century, Belozero was located 17 km east of its current location, at the source of the Sheksna River, where it flows out of Lake Beloye. At that time, there was also a kremlin in the city, which has been almost completely lost, especially after the flooding of the old Belozero area in the 1960s due to the construction of the Cherepovets hydrojunction in the village of Sheksna, as part of the Volga-Baltic waterway. Fortunately, detailed archaeological studies were conducted before the flooding.

The earthen rampart of the kremlin has been preserved in excellent condition and still impresses with its scale. Inside the kremlin, some buildings have survived, including the Spaso-Preobrazhensky Cathedral. Due to the good preservation of the earthen rampart, unlike other cities in Russia, the Beloozersky Kremlin cannot be considered lost.

Where the former blind towers stood, small extensions of the rampart are now visible, and the places where the gates were located look like "depressions" in the rampart. Eight towers are listed clockwise when looking at the photograph. The Petrovskaya tower is on the left, the corner one, and the Ilyinskaya blind tower is on the right, the corner one, by the large pond.

Currently, the main entrance to the kremlin area is a three-span arched bridge made of red brick, built in the 19th century on the site of the former Bogoslovskaya tower.
