Yes, that is a piano in a parking spot and a putt-putt golf game next to the sidewalk.

A Park(ing) Day space near Metro Center. (Bill O'Leary/WASHINGTON POST)

Park(ing) Day began in 2005, when a San Francisco based art studio dedicated to environmental projects set up a park for two hours in a metered space. Since then, the event has spread, with temporary parks popping up in 162 cities and 35 countries over the past seven years. Now, the third Saturday in September is designated as the day for creating temporary green space.

So what can a person create with limited time and only a small area of asphalt to work with? Check out the photos below of improvised parks in D.C. and around the world.
