Following the political liberalization of the Polish October in 1956, it became possible to introduce modernist style in architecture. Polish architects were allowed to visit Stockholm to learn about the newest solutions in urban design. As a result, the so-named "Swedish" apartment block was developed according to Le Corbusier guidelines. Among other buildings from that era, the "Światowid" cinema is worth noting. In the 1980s, the first postmodernist buildings were built, a notable example being the Centrum E housing estate. In the 1970s and 1980s, many apartment blocks were built using plattenbau.
