At 24 inches (61 centimeters) in diameter, this is the world’s smallest dedicated park. Located in the median of Southwest Naito Parkway at Taylor Street, its story began when a journalist for the Oregon Journal, Dick Fagan, got tired of looking at an empty hole (for a lightpole that never came) below his ofﬁce window. He decided to plant ﬂowers in the hole, then write his Mill Ends column about the capers of the ﬁctitious park resident, a leprechaun named Patrick O’Toole. The park was dedicated on St. Patrick’s Day in 1948 and became an official city park in 1976.
Over the years, events have been held at the park and contributions have been made to the park, such as the small swimming pool and diving board for butterflies, many statues, a miniature Ferris wheel (which was brought in by a normal-sized crane), and the occasional flying saucer.
