The University Children's Hospital in Tiršova Street in Belgrade was designed by the architect Milan Zloković, one of the most prominent representatives of modern architecture in Serbia. It is one of the most significant works of this architect and Serbian modern architecture in general. It was built from 1936 to 1940, but, due to damage during the Second World War, it began operating at full capacity only in 1947. Its construction is also important in the social sense, if we keep in mind that the premises of the children's hospital were originally located in inadequate barracks. The director of the clinic, MD Matija Ambrožić, who was also signed as an associate on Zloković's projects, had a special role in the realization of the entire project. The clinic is designed as a multi-storey building with characteristic elements of modernist architecture, such as free organization of the base, facade without ornamentation, flat roof, as well as roof terraces, which, together with other terraces, had functional significance and were intended for patient’s sunbathing and their connection with nature. The harmonious forms of the hospital’s architectural solution were grossly disrupted by inadequate additions during the 1990s.
