Windmills have been around since the times of the ancient Greeks; but nowadays, the country that's probably most associated with them is the Netherlands (apparently, windmills helped drain its low-lying lands). Rotterdam-based architectural firm 2012Architecten took this playful association further in doing this neat renovation of a derelict playground, using recycled wind turbine parts.
Each recycled rotor blade is cut up or erected to have its own function or character: there's a slide tower, a watchtower and so on; between the four towers hangs a climbing net, which also serves to catch wayward balls from being thrown into neighbouring gardens.
With old windmills and modern wind turbines still very much a part of the Dutch landscape, this colourful playground takes a historical piece of the Dutch identity and deftly integrates it into the city. More information over at 2012Architecten.
