A visit to St Petersburg warrants a trip to the Russian Cruisor Aurora. It might not sound like an exciting journey, but for those interested in military history, the Aurora is a protected/preserved cruisor moored at St Petersburg, now acting as a museum ship.
This ship was one of the Pallada class of cruisors to serve in the Pacific Far East; its main foray was in the Russo-Japanese War in 1905 and the Baltic Seas during WWI, The Aurora was used as a training ship thereafter and had even suffered damage and sunk during WWII. After extensive repairs, it was harboured at Leningrad and still is today (what we know of as St Petersburg).
The Russian Cruisor Aurora is the oldest commissioned ship of the Russian Navy and is still manned by an active service crew. The little bits of history that sustains til today deserve a lot more focus and respect than we bother to give today. If you do make a trip to St Petersburg, remember to board and explore this cruisor!
