Ostankino Tower - the tallest free-standing structure in Eurasia

For a long time the view of the city was dominated by numerous churches. The look of the city changed drastically during Soviet times, mostly due to Joseph Stalin, who oversaw a large-scale effort to modernize the city. He introduced broad avenues and roadways, some of them over ten lanes wide, but he also destroyed a great number of historically significant architectural works. The Sukharev Tower, as well as numerous mansions and stores lining the major streets, and various works of religious architecture, such as the Kazan Cathedral and the Cathedral of Christ the Saviour, were all destroyed during Stalin`s rule. During the 1990s, however, both the latter were rebuilt.

Architect Vladimir Shukhov was responsible for building several of Moscow`s landmarks during early Soviet Russia. The Shukhov Tower, just one of many hyperboloid towers designed by Shukhov, was built between 1919 and 1922 as a transmission tower for a Russian broadcasting company.[11] Shukhov also left a lasting legacy to the Constructivist architecture of early Soviet Russia. He designed spacious elongated shop galleries, most notably the Upper Trade Rows (GUM) on Red Square,[11] bridged with innovative metal-and-glass vaults.

Stalin, however, is also credited with building the The Seven Sisters, which are comprised of seven, cathedral-like structures. A defining feature of Moscow`s skyline, their imposing form was allegedly inspired by the Municipal Building in New York, and their style - with intricate exteriors and a large central spire - has been described as Stalinist gothic architecture. All seven towers can be seen from most elevations in the city; they are among the tallest constructions in central Moscow apart from the Ostankino Tower which, when it was completed in 1967, was the tallest free-standing land structure in the world and today remains the world`s second-tallest.

The Soviet policy of providing mandatory housing for every citizen or their family, and the rapid growth of the Muscovite population in Soviet times, also led to the construction of large, monotonous housing blocks, which can often be differentiated by age, sturdiness of construction, or `style` according to the neighborhood and the materials used. Most of these date from the post-Stalin era and the styles are often named after the leader then in power - Brezhnev, Khrushchev, etc - and they are usually ill-maintained. The Stalinist-era constructions, usually in the central city, are massive and usually ornamented with Socialist realism motifs that imitate classical themes. However, small churches - almost always Eastern Orthodox - that hint on the city`s past still dot various parts of the city. The Old Arbat, a popular tourist street that was once the heart of a bohemian area, preserves most of its buildings from prior to the twentieth century. Many buildings found off the main streets of the inner city (behind the Stalinist façades of Tverskaya Street, for example) are also examples of the bourgeois decadence in Tsarist times. Ostankino, Kuskovo, Uzkoye and other large estates just outside Moscow originally belong to nobles from the Tsarist era, and some convents and monasteries, both inside and outside the city, are open to Muscovites and tourists.

Attempts are being made to restore many of the city`s best-kept examples of pre-Soviet architecture. These revamped structures are easily spotted by their bright new colours and spotless facades. There are a few examples of notable, early Soviet avant-garde work too, such as the house of the architect Konstantin Melnikov in the Arbat area. Later examples of interesting Soviet architecture are usually marked by their impressive size and the semi-Modernist styles employed, such as with the Novy Arbat project, familiarly known as "false teeth of Moscow" and notorious for the wide-scale disruption of a historic area in the Moscow downtown involved in the project.

Like in London, but on a broader scale, plaques on the house exteriors will inform passers-by that a well-known personality once lived there. Frequently the plaques are dedicated to Soviet celebrities not well-known to the outside world. There are also many `house-museums` of famous Russian writers, composers, and artists in the city.
