For the 400th anniversary of Madrid’s Plaza Mayor, urban artist SpY (previously) transformed the bustling square into a centralized place of respite. The temporary park titled Cesped, or “Grass,” was created by bringing in more than 35,000 square feet of sod, which formed a perfect green circle at the center of the pedestrian plaza. Over the course of its four day installation last fall more than 100,000 visitors lounged, played, and rested in the celebratory work.
You can watch a time-lapse installation of the project on the Madrid-based artist’s website, and view more urban interventions on his Instagram. (via designboom)
