Samuel Lewis House in Mansfield, Ohio is a Greek revival building. It was listed on the National Register of Historic Places in 1982.
In 2013 it was The Olde Stone House, a bed and breakfast inn.
It is built of brown and orange-streaked sandstone from the Mansfield area, and was deemed to be the largest and best-preserved antebellum sandstone house in Richland County. It was built as a one-and-a-half-story sandstone house before 1835 when it was bought by Samuel Lewis, who expanded it in 1837.
In 2017, the inn was reopened under new management and a new name. It currently operates as "The Safe House Bed and Breakfast." The owners, Christina and Jake Simpkins, purchased the property in 2015.
