Chestnut Hill

Chestnut Hill is still stereotypically known as one of the more affluent sections of Philadelphia. However, there are many residents who fall within lower/middle class incomes.

Chestnut Hill (along with many other towns and farmlands of Philadelphia County) became part of the City of Philadelphia in 1854 as part of the Act of Consolidation, when the County and the City became completely coterminous. In the same year, the Chestnut Hill Railroad opened, making an easy commute to and from Center City.

During the American Civil War, Chestnut Hill was home to Mower U.S. Army General Hospital, constructed to serve Union army soldiers.

From the mid-19th century through the mid-20th, the neighborhood served as the functional equivalent of both a "railroad suburb" and a "streetcar suburb" of Center City; although it was part of Philadelphia, and not a suburb, it was a leafy outlying part functioning much like a commuter town. (It still serves this function, although the streetcars are gone.) The neighborhood contains a wide variety of 19th and early 20th century residential buildings by many of the most prominent Philadelphia architects.
