One of the singular examples of this type of architecture is Centrul Civic, a development that replaced a major part of Bucharest's historic city centre with giant utilitarian buildings, mainly with marble or travertine façades, inspired by North Korean architecture. The mass demolitions that occurred in the 1980s, under which an overall area of eight square kilometres of the historic centre of Bucharest were levelled, including monasteries, churches, synagogues, a hospital, and a noted Art Deco sports stadium, changed drastically the appearance of the city.
