Moscow is the capital of the Russian Federation and, with a population of nearly 9 million, of the world's largest cities. Historical development of the city occurred in a way that defines modern-day Moscow. Moscow emanates outward from the city's center, which includes the area around the Kremlin, and stretches roughly 68 miles to the "Circular Highway". Moscow is dominated by the architecture and majesty of the many churches, palaces, government buildings, and museums that give the city its readily identifiable skyline. Historical records first make mention of Moscow in the 12th Century, and some buildings, particularly the well-known Cathedrals, date back to as early as the 15th Century. Due to its central location and access to water and railways, Moscow is also an economic center for the Russian Federation. Among the chief components of Moscow's economy are textiles, engineering and metal processing, the manufacture of construction materials and chemicals, woodworking, pulp and paper production, and printing.
