One-way to Moscow

Moscow is the capital and largest city of Russia, situated on the Moskva River in Central Russia. The city has a population estimated at more than 13 million residents within city limits, more than 19.1 million residents in the urban area, and more than 21.5 million residents in the metropolitan area. The city covers an area of 2,511 square kilometers (970 sq mi); the urban area covers 5,891 square kilometers (2,275 sq mi); and the metropolitan area covers more than 26,000 square kilometers (10,000 sq mi). Moscow is among the world's largest cities: the most populous city entirely in Europe, the largest urban and metropolitan areas in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow became the capital of the Grand Principality of Moscow, which led the unification of Russian lands in the 15th century and became the center of a unified state. Following the proclamation of the Tsardom of Russia in 1547, Moscow remained the country's political and economic center for most of its history. During the reign of Peter the Great, the Russian capital was moved to the newly founded city of Saint Petersburg in 1712, leading to a decline in Moscow's importance throughout the imperial period. Following the Russian Revolution and the establishment of the Russian Soviet Federative Socialist Republic (Russian SFSR), the capital was moved back to Moscow in 1918. The city later became the political center of the Soviet Union and experienced significant population growth throughout the Soviet period. In the aftermath of the dissolution of the Soviet Union, Moscow remained the capital city of the newly reconstituted Russian Federation and has experienced continued growth. The northernmost and coldest megacity in the world, Moscow is governed as a federal city, where it serves as the political, economic, cultural, and scientific center of Russia and Eastern Europe. Moscow has one of the world's largest urban economies. Moscow has the second-highest number of billionaires of any city (tied with Hong Kong). The Moscow International Business Center is one of the largest financial centers in the world and features the majority of Europe's tallest skyscrapers. Moscow hosted the 1980 Summer Olympics and co-hosted the 2018 FIFA World Cup. The city contains several UNESCO World Heritage Sites and is known for its display of Russian architecture—particularly in areas such as Red Square, as well as buildings such as Saint Basil's Cathedral and the Moscow Kremlin, which serves as the seat of power of the Government of Russia. Russian companies in various industries are headquartered in Moscow, and the city is served by a comprehensive transit network; this includes four international airports, ten railway terminals, a tram system, a monorail system, and the Moscow Metro, which is the busiest metro system in Europe and one of the largest rapid transit systems in the world. More than 40% of the city's territory is covered by gree
