Moscow International Business Center “Moscow City” (Russian: Московский международный деловой центр «Москва-Сити», Moskovskiy mezhdunarodnıy delovoy tsentr "Moskva-Citi")[1][2] is a commercial district in central Moscow, Russia. Located near the Third Ring Road in Presnensky District of Central Administrative Okrug, the Moscow City area is currently under development. The construction of the Moscow IBC is taking place on the Presnenskaya embankment of the Moscow River approximately 4 kilometers (2.5 mi) west of Red Square, and just east of the Third Ring Road. The project occupies an area of 60 hectares,[3] the territory chosen being the only area in central Moscow that can accommodate such a project. Before construction began, the area had been an old stone quarry where most of the buildings were old factories and industrial complexes that had been closed or abandoned.

In order to manage the project, a public company, CITY, was created in 1992 in order to oversee the initial creation and development of Moscow City as well as its subsequent usage. CITY is also a general contractor and both landlord and leaser. Overall responsibility for the architectural planning and design of Moscow City belongs to the architectural studio No. 6, which is a part of the large Moscow practice Mosproject-2 named after Mikhail Vasilyevich Posokhin. This group, headed by Gennadiy Lvovich Sirota, who is officially the Chief Architect of Moscow City, is in charge of overseeing the design of the complex as a whole and agreeing the details of individual projects. Each building lot has its own investor and architect. By 2014 the volume of investments in Moscow City was approximately $12 billion.

The Moscow IBC is expected to become the first zone in Russia to combine business activity, living space and entertainment in one single development.[3] The Moscow government first conceived the project in 1992.[5] An estimated 250,000 – 300,000 people will be working in, living in, or visiting the complex at any given time.[3] MIBC includes 6 skyscrapers with maximum height of 300 meters or more (Shanghai has 5, Hong Kong has 6, Chicago has 6, New York has 8). Europe's tallest building, the Federation Tower, is in the Moscow IBC. The complex also includes the second-tallest, third-tallest, fifth-tallest, sixth-tallest, and seventh-tallest buildings in Europe. By 2016 twelve of twenty-three planned facilities of MIBC were already built, seven buildings are in construction and four are in the design stage
