One of the most beautiful churches on the Vasilievsky Island is the Dormition Church which is part of the podvorye (embassy church) of the Svyato-Vvedenskaya Optina Hermitage in Kozelsk. The five-dome church was built in the Russian Revival architectural style between 1895 and 1897 according to a plan by architect Vasili Kosyakov. Before being attached to the Optina Hermitage, the podvorye served the Kievo-Pecherskaya Lavra in Kiev and before than the Troitse-Sergieva Lavra in Sergiev Posad. The church was closed between 1935 and 1991 and during this time it was used as an indoor ice-rink.
