Philadelphia, by Easburn, Surveyor General of Pennsylvania


The map presented here shows Philadelphia in around 1776. The city was at that time the meeting place of the Continental Congress, making it the capital of the new American republic. The map was printed in Paris in 1777 by George-Louis Le Rouge (born 1712), royal geographer to King Louis XV, based on a map by Benjamin Easburn, surveyor general of Pennsylvania. It is oriented with north toward the right, and indexed for local points of interest. This map shows wharves, streets, houses, parks, cemeteries, ferries, and forts as well as a library, college, jail, parade ground, poorhouse, and hospital. It also indicates the locations of the churches of a variety of denominations, including Roman Catholic, Lutheran, German Calvinist, Presbyterian, Anabaptist, Moravian, and a Swedish church, along with several meeting houses and other institutions associated with the predominant Quaker (spelled here as “Quaquer”) community. The map shows the Delaware River, Windmill Island, and part of the New Jersey shore across the river from Philadelphia. Scale is indicated in toises, an old French unit measuring about 1.95 meters, and pieds, equivalent to 1/6th of a toise or an English foot. The map is from the Rochambeau Collection at the Library of Congress, which consists of 40 manuscript maps, 26 printed maps, and a manuscript atlas that belonged to Jean-Baptiste-Donatien de Vimeur, comte de Rochambeau (1725‒1807), commander in chief of the French expeditionary army (1780‒82) during the American Revolution. Some of the maps were used by Rochambeau during the war. Dating from 1717 to 1795, the maps cover much of eastern North America, from Newfoundland and Labrador in the north to Haiti in the south. The collection includes maps of cities, maps showing Revolutionary War battles and military campaigns, and early state maps from the 1790s.
