I got a question for you: Moscow is situated on the Moskva River in the Central Federal District of European Russia, making it Europe's most populated inland city. The city is well known for its architecture, particularly its historic buildings such as Saint Basil's Cathedral with its brightly coloured domes. With over 40 percent of its territory covered by greenery, it is one of the greenest capitals and major cities in Europe and the world, having the largest forest in an urban area within its borders -- more than any other major city -- even before its expansion in 2012. The city has served as the capital of a progression of states, from the medieval Grand Duchy of Moscow and the subsequent Tsardom of Russia to the Russian Empire to the Soviet Union and the contemporary Russian Federation.
