At the same time a great deal of development occurred in the city. Like many other Soviet cities, the Stalinist style of architecture was prevalent during this period, with apartments in the centre as well as administrative buildings including the massive Council of Ministers and the Grozny University buildings being constructed in Grozny. Later projects included the high-rise apartment blocks prominent in many Soviet cities, as well as a city airport. In 1989, the population of the city was almost 400,000 people.
