Known as the �Queen City of the Ozarks,� Springfield was founded in 1829 and became the seat of Greene County in 1835. Beginning in 1870, Springfield served as a railroad hub that connected the Ozarks culturally and financially to Kansas City, St. Louis, Chicago, and points along the East Coast. In 1938, Route 66 became part of the city�s history when the legendary highway came through the public square on College Street. Built on land donated by Springfield founder John Polk Campbell, the square continues to be a vital part of the city�s culture and economy.
