Philadelphia, site of both Continental Congresses, was one of the most urban, advanced cities in America in the eighteenth century. Drawn by George Heap, a surveyor and city coroner of Philadelphia, and Nicolas Scull, Surveyor General of the Province of Pennsylvania and a friend to Benjamin Franklin, this map shows streams, roads, and names of the landowners in the vicinity of Philadelphia. The bottom of the map contains an illustration of the State-House or Independence Hall, home of the second Continental Congress and the Federal Convention of 1787.
