Interesting History:
By the late 1700s the square was surrounded by brickyards as the area’s clay terrain was better suited for kilns than crops. In 1825 the square was renamed in honor of Philadelphian David Rittenhouse, the brilliant astronomer, instrument maker and patriotic leader of the Revolutionary era.
A building boom began by the 1850s, and in the second half of the 19th century the Rittenhouse Square neighborhood became the most fashionable residential section of the city, the home of Philadelphia’s “Victorian aristocracy.” Some mansions from that period still survive on the streets facing the square, although most of the grand homes gave way to apartment buildings after 1913.
In 1816, local residents loaned funds to the city to buy a fence to enclose Rittenhouse Square. In the decade before the Civil War, the Square boasted not only trees and walkways, but also fountains donated by local benefactors – prematurely, it turned out, for the fountains created so much mud that City Council ordered them removed. The square’s present layout dates from 1913, when the newly formed Rittenhouse Square Improvement Association helped fund a redesign by Paul Philippe Cret, a French-born architect who contributed to the design of the Benjamin Franklin Parkway and the Rodin Museum. Although some changes have been made since then, the square still reflects Cret’s original plan.
