Where many see patches of asphalt and a source of potential tickets, those participating in PARK(ing) Day 2015 view parkings spots as their canvas. The concept—paying for a metered parking space for a single day and using it as a site for an urban intervention and temporary installation—started with a single spot in San Francisco in 2005. San Francisco art collective Rebar, looking to test ideas of temporary design and car-centric urban planning, took over a parking spot, covering it in grass turf and setting up a park bench and a potted tree. The concept has steadily grown into a global event, with hundreds of people staging similar pop-up displays on the third Friday in September every year and temporarily reclaiming, spot by spot, some additional open space. With today's event taking up spots in cities around the globe, we checked Instagram to find some of the best examples of temporary installations taking part in PARK(ing) Day 2015.
