Mill Ends Park is a tiny urban park located in the median strip of SW Naito Parkway, approaching esplanade along the Willamette River near SW Taylor Street in downtown Portland, Oregon, United States. The park is a small circle 2ft across, with a total area of 452sqin. It is the smallest park in the world, according to the Guinness Book of Records, which first granted it this recognition in 1971.HistoryIn 1948 the site that would become Mill Ends Park was intended to be the site for a light pole. When the pole failed to appear and weeds sprouted in the opening, Dick Fagan, a columnist for the Oregon Journal, planted flowers in the hole and named it after his column in the paper, "Mill Ends" (a reference to leftover irregular pieces of wood at lumber mills). Fagan's office in the Journal building overlooked the median in the middle of the busy thoroughfare that ran in front of the building (then known as SW Front Avenue).The park was dedicated on St. Patrick's Day, 1948, as "the only leprechaun colony west of Ireland", according to Fagan.LegendFagan told the story of the park's origin: He looked out the window and spotted a leprechaun digging in the hole. He ran down and grabbed the leprechaun, which meant that he had earned a wish. Fagan said he wished for a park of his own, but since he had not specified the size of the park in his wish, the leprechaun gave him the hole. Over the next two decades, Fagan often featured the park and its head leprechaun in his whimsical column. Fagan claimed to be the only person who could see the head leprechaun, Patrick O'Toole.
