Rodney Square Historic District


Today’s Rodney Square evolved from a 1 ½ acre parcel of land bounded by West 10th, North Market, West 11th and North King Streets which was assembled from six separate parcels by the Borough of Wilmington between 1825 and 1832.

Wilmington’s first water reservoir was situated in this block from 1827 to 1877. Also located on the site were the Water Department offices, a fire engine house and the City Engineer’s office. Following the relocation of the reservoir to the Cool Spring area, the New Castle County Court House was built in the middle of this parcel, opening in 1881 and remaining until 1919.

During the early 1910s, DuPont Company Vice President Pierre S. duPont and his personal assistant John Jacob Raskob developed a master plan for the Square that would transform the location into the civic center of Wilmington, complete with open space and special features that would unify the entire surrounding area and buildings into a single scheme.

Rodney Square’s design was influenced by the “City Beautiful Movement,” an urban planning movement led by architects, landscape architects and civic reformers at the turn of the 20th century to improve social order by introducing more beauty in the urban landscape, thereby encouraging civic pride and engagement.

Construction of the Square (then called Rodney Square Park) began in 1915 and was completed in 1921. The defining symbol of the Square, the equestrian statue of Caesar Rodney created by James E. Kelly, was dedicated on July 4, 1923. The statue commemorates Rodney’s ride from Dover to Philadelphia on July 1-2, 1776 to cast the deciding vote in the Continental Congress for independence from England.

Rodney Square and its four surrounding buildings (along with the Caesar Rodney statue and the Nemours Building) were all placed on the National Register of Historic Places in November 2011.

Surrounding Buildings

DuPont Building
1007 North Market Street

Wilmington’s tallest building and the anchor building of the Square, the DuPont Building, began construction in 1907 as a 12-story office building in the Italian Renaissance style. Multiple phases of construction continued between 1911 and 1931. Its design influenced the style of the other buildings facing the Square.

New Castle County Court House and City Hall
1000 North King Street

On the East is the former New Castle County Court House and Wilmington City Hall designed in the symmetrical Classical Revival style and constructed between 1914 and 1916. Also known as the City-County Building, this was the first civic building to be built as part of the DuPont vision for Rodney Square. Major interior renovations in the latter half of the 20th century left only the prominent marble staircases intact. Rear additions were made in 1960 and 1980, and a major renovation in 2012 fitted the building for law offices.

Wilmington Institute Free Library
10 East 10th Street

On the south on 10th Street is the award-winning Beaux Arts style Wilmington Institute Free Library, initially designed in 1917, which opened in 1923.

United States Post Office, Court House, Custom House
1100 North Market Street

The final civic building to be built on the Square was the former U.S. Post Office, Court House and Customs House, constructed during the Works Progress Administration era of 1935 and 1937. In 1983, a 14-story addition was added at the rear of the Neo-Classical building to accommodate the offices of Wilmington Trust.

Nemours Building
1007 North Orange Street

Off the Square itself but part of the Rodney Square Historical District is the Nemours Building, begun in 1935. This 14-story building was constructed for the DuPont Engineering Department on the block located to the west of the DuPont Building. The Moderne style of the building matched that of the 1930 addition to the DuPont Building, and the two buildings were once connected by a tunnel and a bridge.

“It’s time to restore this grand public square to not only its original glory, but to go beyond that vision to one that will improve the square and allow its upkeep to be more manageable while making the square itself more beautiful, attractive and useful.”

Mike Purzycki, Wilmington Mayor

“This is an exciting opportunity to restore the Square to its historic role as a centerpiece of downtown Wilmington; as first constructed in the 1920s.”

John Sisson, CEO of Delaware Transit Corporation

“Across Wilmington, we’re making investments in neighborhoods, in city schools, and critical infrastructure to help make sure that all Wilmington residents see and feel the benefits of Wilmington’s success.”
