* After visiting Peterhof (the place built by Peter the Great to emulate Versailles)
, Catherine the Great's palace and The Armory (it houses all of the jewels, gowns, carriages of the Tsars) and learning of the serf system they had set up, there is no wonder there was a revolution which toppled the Tsar system. After having been to Versailles and knowing what I know about the French kings, no surprise about a revolution there either.
* Much of what you learn on your tours revolves around either Tsarist history or WWII. There are monuments all over both St. Petersburg and Moscow honoring their war dead and the great achievement of the "red" army.
* "Red" in Russia signifies beauty.
* The siege of Leningrad (St. Petersburg) by the Germans lasted 872 days with 1 1/2 million people and soldiers perishing. After all the birds, rats and pets had been eaten, there were stories of cannibalism. 27 million Russians died during the war.
