Park(ing) day is a community of artists, activist, students and everyday people who, on September 21, every year and across the world, collaborate to transform parking spaces into green and friendly spaces. They invite reflections and discussions on the significance of nature and quality of life in urban areas. Park(ing) day encourages people to take over public spaces, reclaim their space, and imagine how sustainable and green cities can be.
In 2005, Rebar, a design studio in San Francisco, transformed a single metered parking space into a temporary public park. The area where this two-hour park took place was one that lacked public open space. This was the first Park(ing) Day project.
