Manayunk was originally a community in Roxborough Township, Philadelphia County, situated near the Schuylkill River, south of the Wissahickon Creek. The land that would become Manayunk was first bought from William Penn in 1685-1686 and then transferred to the family of Wigard Levering. A large part of that land was then sold to Levering's son, Jacob, in 1716. Soon, the younger Levering built the first house in Manayunk, on the north side of Green Lane, west of Silverwood Street. The growing town was known as Flat Rock in 1810, from a peculiar flat rock lying on the lower side of the bridge. This was subsequently called Flat Rock Bridge. The bridge was part of the Flat Rock Turnpike connecting Roxborough Township with Merion Township. The bridge was demolished in 1850.
