Split 3 is a city unit in Split.
During the second half of the 20th century, the population of the city of Split grew at an incredible rate. For this reason, there is a need for new housing, which is why in 1968 a tender was announced for the construction of a new part of the city, which in 1969 won the urbanists from the Urban Institute of Slovenia - Vladimir Music, Marjan Bezan and Nives Starc with the idea of building a new settlement Split 3. The project included the construction of residential streets with a larger street, blocks of tall residential buildings with apartments facing south overlooking the sea, and low-rise buildings for individual housing. On the ground floors, and especially at intersections and squares, the idea was to build business premises for various purposes, and between the streets to create green areas for recreation in which there would be kindergartens and schools. In addition, a space was designed for shops, business premises, banks, embassies, health center, hotel, theater, concert hall, cinema, museum, gallery, library, archive, etc. Unfortunately, during its construction, the JNA, as the most powerful investor, met is its housing needs, and Split also received the organization of the Mediterranean Games in 1979, so it directed its potentials towards this obligation, while Slovenian urban planners returned to Ljubljana, leaving the Split III project without any author's urban supervision. The consequences were that the urban planning institute lost its real job, and was satisfied with individual, smaller projects, the number of employees was reduced, and to this day it has not recovered. However, although not fully completed today, Split III still lives in the idea of population and is used in public discourse among its inhabitants, but also much more widely, in the media, mentioned at professional gatherings, etc. The project was analyzed by experts around the world. books, articles, reviews were written, reviews were written, and a film was made. Award-winning Croatian architect Luka Skansi called the project Diocletian's Palace of the 20th century.
Today's streets that include this project are the streets of Ruđer Bošković, Marin Getaldić, Juraj Dobrila, Rikard Katalinić Jeretov, Faust Vrančić, the part of Matica hrvatska Street that passes through this part of the city and Kroz Smrdečac.
