History: Then And Now, Moscow, Russia

Administrative okrugs of Moscow: 1. City of Zelenograd 2. Northern 3. North-Eastern 4. North-Western 5. Central 6. Eastern 7. South-Eastern 8. Southern 9. South-Western 10. Western
The entire city of Moscow is headed by one mayor (Sergey Sobyanin). The city of Moscow is divided into 10 administrative okrugs and 123 districts.
The Russian capital's specific town-planning development began to show as early as the 12th century, when the city was founded. The central part of Moscow grew by consolidating with suburbs in line with the medieval principles of urban development, when strong fortress walls would gradually gird along the circle streets of adjacent new settlements. The first circular defense walls set the trajectory of Moscow's rings, laying the groundwork for future town-planning of the Russian capital.
The following fortifications served as the city's circular defense boundaries at some point in history: the Kremlin walls, Zemlyanoy Gorod (earthwork town), the Kamer-Kollezhsky Rampart, the Garden Ring, and the small railway ring. The Moscow Automobile Ring Road (MKAD) has been Moscow's boundary since 1960. Also in the form of a circle are the main Moscow subway line, the Ring Line, and the so-called Third Automobile Ring, which was completed in 2005. Hence, the characteristic radial-circle planning continues to define Moscow's further development. However, contemporary Moscow has also engulfed a number of territories outside the MKAD, such as Solntsevo, Butovo, and the town of Zelenograd.
