The Boulevard Ring (Russian: Бульва́рное кольцо́; transliteration: Bulvarnoye Koltso) is Moscow's second innermost ring road (the first is formed by the Central Squares of Moscow running along the former walls of Kitai-gorod).
Boulevards form a semicircular chain along the western, northern and eastern sides of the historical White City of Moscow; in the south the incomplete ring is terminated by the embankments of Moskva River.
The wall itself was razed in 1760, and despite the royal decrees to keep the site clear, the area was soon built over with private and state property.
The Fire of Moscow destroyed many of those buildings, allowing the city planners to replace them with wide green boulevards.
These plans to properly terminate the ring through Yakimanka and Zamoskvorechye districts, proposed in 1935, periodically resurface in city planners' discussions.
