The Tolstoy House is a large and well-known apartment building in St. Petersburg, located at 15-17 Rubenstein Street and 54 Fontanka Embankment. The building was designed by Fyodor Lidval[1] in the “Northern Modern” style. The building was constructed in 1910-1912 under the aegis of Major-General Count Mikhail Pavlovich Tolstoy,nephew of the 1812 war hero P. A. Tolstoy. After Tolstoy's death in 1913, ownership devolved to his widow Countess Olga Tolstoy (born a princess of the Vasilchikov family, daughter of Prince Alexander Illarionovich Vasilchikov, a second in the famous 1841 duel between Mikhail Lermontov and Nikolai Martynov)
