In 1978, the City of Owosso commemorated the 100th anniversary of James Oliver Curwood’s birth with a celebration centered around his castle. Since then, it has grown to three full days of activities for the entire family, with hundreds of volunteers working all year long and dozens of community organizations taking part. The festival commemorates Curwood in particular and Owosso’s heritage in general and provides a weekend of fun, relaxation and homecoming.
