As television presenter Simon Reeve explores Russia in a new three-part BBC programme airing tonight, we highlight 59 interesting facts you might not have known about one of the world's most intriguing countries.
For more on the country, including the best hotels to stay in while you're there, see our guide.
1. The Astoria hotel in St Petersburg is where Hitler planned to hold a huge celebratory banquet once he'd conquered the city.
2. Its greatest museum - The Hermitage, also in St Petersburg - is home to around 70 cats, which guard its treasures against rodents. The tradition dates back to a 1745 decree of Empress Elizabeth, the daughter of Peter the Great, founder of St. Petersburg. The museum also has almost 14 miles of marbled corridors.
3. Subbotnik is the day when residents of Russian cities volunteer to sweep up and tidy the streets. It started after the revolution but still happens today.

4. The name Red Square has nothing to do with communism, but derives from the word "krasnyi", which once meant "beautiful".
5. The icicles hanging from the gutters in Moscow in winter are so enormous that the pavements below are cordoned off - as they'd kill you if they fell on your head.
6. There is a bronze sculpture of a dog with a shiny nose at Ploshchad Revolutsii metro station - it is shiny because it's good luck to touch it.
7. That isn't the only sculpture of a dog in Russia - there's also this monument to Laika, the hound that went to space in 1957.

11. In St Petersburg, next to the bridge to reach the Peter and Paul Fortress, is a statue of a hare which commemorates the large number of hares that used to live on the island, and their battle against the floods that plagued the city during the 18th and 19th centuries. It's considered good luck to hit it with a coin.

21. In the vault/museum beneath the Monument to the Heroic Defenders of Leningrad, the only sound is the steady ticking of a metronome - it is the noise that played out on local radio during the seige so that residents knew the city was still alive.

27. There's a restaurant in Moscow staffed entirely by twins.
28. It's not all tundra and taiga - you can go trekking on volcanoes.
29. Foreigners pay a higher entrance fee at many tourist sites. It’s unfair, but there’s nothing you can do, and there is little point in complaining. Best to laugh it off, and picture Roman Abramovich paying five times less than you under the “discounts for Russian citizens” scheme.
30. Postnik Yakovlev is best known as the man behind St Basil's Cathedral. Legend has it that Ivan the Terrible blinded him afterwards, so he could never build anything to rival it.

35. Western leaders are not welcome in at least one airport duty free shop.
36. In the White Dining Room in the Hermitage Palace there's a clock on the mantelpiece. It was stopped at 2.10am on the night of October 25,1917, when Kerensky’s provisional government, which had held power since the February revolution, was arrested by the Bolsheviks - it is the moment Russia slipped into to communism.

To quell the ensuing uproar, Moscow despatched investigators, who concluded that the young boy fell, accidentally stabbing himself (“Seven times!” add locals, wryly) in the process.
