Manayunk ( ) is a neighborhood in the section of Lower Northwest Philadelphia in the state of Pennsylvania. Located adjacent to the neighborhoods of Roxborough and Wissahickon and also on the banks of the Schuylkill River, Manayunk contains the first canal begun in the United States (although not the first completed, due to budget problems). The area's name is derived from the language of the Lenape Indians (later called the Delaware Indians by Europeans). In 1686-dated papers between William Penn and the Lenape, the Lenape referred to the Schuylkill River as "Manaiung", their word for "river", which literally translates as "place to drink"; the word was later altered and adopted as the town's name. Although historically a working class community, in recent years the neighborhood has been substantially gentrified. While there is still a working class population within the neighborhood, the population has shifted to younger, upper middle class professionals and families. Additionally, the nightlife in Manayunk draws visitors from all over the Delaware Valley, as well as international visitors. History Pre-industrial Manayunk Borough 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. The settlement got its nineteenth-century identity from the construction of the dam, canal, and locks by the Schuylkill Navigation Company. The Manayunk section was finished at the end of 1818. Since the power provided by the water was extensive, the Navigation Company sought lessees of the power for use in mills and factories. In 1819, Capt. John Towers opened the first mill that used the canal's water power. After that, purchases of water-power and the erection of mills and factories greatly increased. The area became important as a manufacturing village. It had a very large textile industry,
