Notable examples of post-war architecture include the Palace of Culture and Science (1952–1955), a soc-realist and art deco skyscraper based on the Empire State Building in New York. The Constitution Square with its monumental socialist realism architecture (MDM estate) was modelled on the grand squares of Paris, London, Moscow and Rome. Italianate tuscan-styled colonnades based on those at Piazza della Repubblica in Rome were also erected on Saviour Square.
