This paper deals with Business tower Zagrepčanka designed by Slavko Jelinek and Berislav Vinković, built from 1969 until 1976 by the project office AGI-46. The building investor and constructor was the construction company Vranica from Sarajevo. Zagrepčanka was one of the first business towers constructed in Zagreb during the second half of the 20th century intended for the market, very quickly becoming one of the city’s symbols. Despite being an exceptional structure of the Croatian architecture of the socialist-era and recognised as such by Register of Cultural Property of the Republic of Croatia 2006, the significance of Business tower Zagrepčanka as one of the first business towers in socialist state is still not sufficiently researched Based on published literature, archival documents, professional journals and daily newspapers this paper describes in detail Business tower Zagrepčanka aiming to research its significance in the context of the city and the state itself, as well as its place in the phenomenon of bussines tower construction in former Yugoslavia. Its architectural design makes Business tower Zagrepčanka a unique building in Croatian architecture. Built in the seventies it shows the progress of the modern tehnology and its stature makes it distinctive part of the city. Apart from its exceptional architecture Zagrepčanka through its name shows the tendency toward a creation of the recognizable structure that emphasizes the importance of the city and its inhabitants. To the present day Zagrepčanka has retained its memorable place in the city silhouette. Although Zagrepčanka sustained the continuity of its function in contemporary times, new problems arise in the context of its functionality due to the inconsistency of the building to today's standards, which is associated with non-competitiveness in the market of business premises, and insufficient attractiveness of the building and surrounding space. Further investment in the building is required so that in the future it does not remain only at the level of symbol.
