Another interesting fact for you that the famous Red Square in Moscow was translated into English a wrong way. Even many contemporary Russians believe its name (Красная Площадь) really means "Red Square", but it is not correct. It is an old name, and it has to be translated as "Beautiful Square" instead. BTW, the stone which covers the Red Square is not red at all and never was, it is gray in fact.
