Vladimir Nabokov Museum, St. Petersburg

Although this was the childhood home of Lolita's famous author, the rest of his life was spent well away from the place, after his well-to-do family fled the Bolshevik revolution in 1917. Only recently re-opened to the public, the museum, if you can call it that, doesn't have a lot to offer the visitor. Apart from a grand piano in the large entrance hall and a couple of chairs taken up by attendants, there is as yet no furniture and no genuine taste of a pre-revolutionary bourgeois lifestyle. The place is worth popping into as there may be an exhibition by a local artist on display. Alternatively, you can scan some photos depicting hotels and regions Nabokov stayed in whilst in France, which are of mild interest. A history of the house since the revolution can be read in another room, but unfortunately only in Russian.
