The Peti Parkić case study in Belgrade serves as a significant example of how community-led initiatives can successfully safeguard vital public urban spaces. In 2005, when a private investor planned to replace a 3500 m² neighborhood park with a mixed-use commercial complex, local residents mobilized a rapid, unified response. Under the banner of the newly formed Initiative Committee for the Defense of Peti Parkić, an intergenerational collective of citizens organized structured protests, extensive petition drives, media campaigns, and collaborative cultural actions to contest the development.

Their persistent sixteen-year campaign (2005–2021) underscores the capacity of long-term civic engagement to reshape local urban governance. Residents actively pursued formal legal challenges, forged strategic alliances with external organizations and public figures, and maintained a continuous dialogue with municipal and city authorities. Despite conflicting property interests and highly complex administrative procedures, this sustained community advocacy ultimately led the City of Belgrade to cancel the commercial development plans, reclaim the parcel, and execute a collaborative, resident-approved spatial revitalization. Today, the park stands as a functional community asset, offering integrated playgrounds, green infrastructure, and dedicated spaces for public socialization, and serving as a clear structural model for the “right to the city” paradigm and the essential role of public open spaces in enhancing neighborhood-scale quality of life.
