The Pioneer's town, today the City of youth, was built in the first post-war years (1948-1951) in Granešina near Zagreb, stretching along the extreme slopes of Medvednica. The thematic structure was built in accordance with the then new pedagogical idea and under the influence of the existing practice of the then communist states of Europe. Specifically children's areas such as pioneer camps and towns are often linked to contents such as the pioneer railway and are intended for educational, educational, sports-recreational and cultural contents of pioneer organizations. The construction and appearance of Pioneer's town near Zagreb was influenced by a number of political, economic and social factors in the early post-war years, while the project itself was signed by urban planner Josip Seissel and architect Ivan Vitić, and its horticultural design by Zvonimir Frölich and Pavao Ungar. For more than 70 years, the Pioneer's town complex has served as a place of education, recreation and leisure for all generations, but mostly for children of preschool and school age. The renovations carried out on the complex over the decades included mostly rehabilitation and reconstruction works along with interior adaptations, with the most recent procedures carried out in 2003-2004. years. In 2005, the complex was declared a protected cultural asset and entered as a cultural-historical entity in the Register of Cultural Assets of the Republic of Croatia. Since the completion of the renovation in 2004, no major construction works have been carried out on the area of ​​the complex, and the existing revitalization project of the City of youth was only started until the Zagreb earthquake in 2020.
