The world's smallest park is Mills End Park in Portland, Oregon . . . it's a two-foot circle!

Oregon Journal columnist Dick Fagan started "Mills End Park" when he planted flowers in a 2x2-foot hole filled with weeds. The hole was where a light pole was supposed to be installed in 1948, but the light never appeared. He named the park after his column.

Fagan wrote in his column a leprechaun named Patrick O'Toole lived in the park and gave it to Fagan.

The park was dedicated on St. Patrick's Day in 1948 as the only Leprechaun Park west of Ireland.
