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.
