World’s Smallest Park, Mill Ends Park
Mill Ends Park is located on the median of SW Naito Parkway in downtown Portland. The nearest cross street is SW Taylor. All 452 square inches of the park were temporarily relocated while SW Naito Parkway was under construction in 2006-07.
It’s now back in place and growing as strong as ever.
The park was first created by Dick Fagan on St. Patrick’s Day, 1948 by taking advantage of a hole in the ground that was meant for a light pole that never got installed. Fagan wrote about the park in the now defunct Oregon Journal for the next two decades.
Mill Ends Park officially entered the City of Portland’s park inventory in 1976 and has been taken care of since then by the City. It still plays host to many events, both full sized and miniaturized.
