At present this is the only composer's museum in St.Petersburg
It occupies a wing of the house 28 on Zagorodny Prospekt, where Rimsky–Korsakov had spent the last fifteen years of his life, from 1893 to 1908. It was here that he composed eleven of his fifteen operas, among them Sadko, The Fairy–Tale of Tzar Sultan, The Tzar's Bride, Kashchey, the Immortal, The Golden Rooster. After the composer's and his wife's death, for fifty years the apartment was shared by several families. Nevertheless, all private belongings, as well as the furniture, have been carefully preserved by the composer's heirs.
