Postane is an urban hub for impact-driven work and collaborative cultural production, based in the historic Galata neighborhood of Istanbul. Located in the renovated British Post Office building, it develops innovative economic models and cultural programs to address social, environmental, and urban challenges. The space features a rooftop permaculture garden where fruits, vegetables, and herbs grow; a solidarity-based, vegan/vegetarian cafeteria; a fair trade unit connecting consumers with local producers and social enterprises; open office spaces; a specialized library; a podcast and video studio; and a multipurpose hall for public and private events. Postane is a proud member of two international networks: • Bertha Spaces  fosters activist spaces in Africa, Europe, and the United States under the principle of “radical hospitality.” Through this network, Postane co-develops strategies for creating resilient community spaces and hosts public programs, knowledge-sharing sessions, and collaborative events. Watch highlights from our Turkish-South African fusion Fair Food Connections dinner here. • The Allianz Foundation Hubs Network connects organizations working on civil society, arts & culture, and climate justice across Europe and the Mediterranean. Postane actively contributes by leading knowledge-exchange sessions on sustainable urban food systems, social economies, scalable models for resilient community-led spaces. Discover here how the kitchens of Autostrada Biennale and Postane Café collaborated in Kosovo to create innovative, vegetarian interpretations of traditional dishes, prepared with locally sourced, seasonal ingredients. This initiative exemplified a sustainable approach to public catering—minimizing local food waste, respecting cultural heritage, and embracing culinary innovation. Postane is developed and operated by the social enterprise Bak Postacı, with the vision of fostering sustainable solutions that integrate community, sustainability, and urban resilience.
