Mill Ends Park is the smallest park in the world. With only 452 squared inches in total area, it is simply the teeniest public park that people can visit.

Created by Dick Fagan on St. Patrick’s Day in 1948, the space was originally for a light pole. However, when the hole was left vacant and weeds started to grow in them, Fagan, who was then a columnist for the Oregon Journal, decided to make it a park instead and named it after the title of his column, Mill Ends.

Fagan said that Mill Ends Park is the one and only leprechaun colony in the west. It was declared an official city park in 1976 and has experienced many remodeling through the years.
