architectural achievements. Spomeniks in Serbia During this period, the Yugoslav break from Soviet socialist realism combined with efforts to commemorate World War II, which together led to the creation of an immense quantity of abstract sculptural war memorials, known today as spomenik Brutalism In the late 1950s and early 1960s Brutalism began to garner a following within Yugoslavia, particularly among younger architects, a trend possibly influenced by the 1959 disbandment of the Congrès Internationaux d'Architecture Moderne. Besides numerous brutalist buildings in the capital, other notable examples can be found in Novi Sad, Priština, Požarevac, Arilje, Užice, Sremska Mitrovica and other parts of the country. Brutalism would be a prevalent architectural style in Serbia, changing the design, scale and use of concrete elements in building construction, up until the end of the 20th century with the breakup of Socialist Yugoslavia. Yugoslav Brutalism in Serbia incorporates elements of modernism, structuralism, metabolism, and constructivism, with later prefabricated buildings moving away from pure exposed concrete brutalist designs.

Architects increasingly focused on building with reference to the architectural heritage of their individual socialist republics in the form of critical regionalism. Growing distinction of individual ethnic architectural identities within Yugoslavia was exacerbated with the 1972 decentralization of the formerly centralized historical preservation authority, providing individual regions further opportunity to critically analyze their own cultural narratives. International Style International Style in Serbia in the later half of the 20th century mostly consists of buildings stripped from most decorative elements, having an emphasis on glass skyscraper styled designs. This trend would continue in the early decades of the 21st century, with some design variations
