Built in 1856, the Mill House Quilt Retreat was once regarded as a grand mansion. It was originally home to the owner of one of Utica’s famous glass factories. Today, it still showcases 11-foot ceilings, inlaid hardwood floors, and a charming wrap-around porch. The house also holds a powerful history, having been part of the Underground Railroad and featuring an escape tunnel for people fleeing enslavement.
