Marysville Historic Home Driving Tour

Welcome to the Marysville Tour of Homes and Buildings presented by Team Marysville in partnership with the Union County Historical Society. In 2019, the City of Marysville will celebrate its 200th anniversary. As part of that celebration, Team Marysville has created a driving tour of interesting homes and buildings in Marysville that serves as a sample of some of our town’s history, heritage, and architecture. Initiated in 2016 with sixteen sites, the tour will be expanded each year through 2019.
