Coastal Monastery of Saint Sergius

The earliest buildings of the monastery, including the pentacupolar cathedral, the outer wall and the towers, were designed by Pietro Antonio Trezzini.

After the Russian Revolution the Soviets suppressed the monastery (1931), destroyed the cemetery and adapted the grounds to serve as a labor camp, or a work farm.

Some of the noblest and richest families of Imperial Russia, including the Galitzines, the Stroganovs and the Yusupovs, patronised the monastery and had their burial vaults on the grounds.

The local cemetery is the burial site of a number of Russian nobles, including the Zubov brothers, Prince Alexander Gorchakov, Duke Peter Georgievich of Oldenburg, and court architect Andrei Stackenschneider.

The graves of the Dukes of Oldenburg and Leuchtenberg, both closely related to the Russian imperial family, were either lost or desecrated during the Soviet period.
