Mill Ends Park in Portland, Oregon is the world’s smallest park at barely two feet across. It was created by journalist Dick Fagan after he saw a light pole removed from the median outside his office that was never replaced, causing weeds to build up in the spot. He planted some flowers there instead and wrote a piece featuring a story about how the park was constructed for a leprechaun colony. It has remained there since its dedication on St. Patrick’s Day, 1948. At one point, it even housed a swimming pool, statues, and a miniature Ferris wheel.
