A Lighthouse for Brandywine Shoal: America's First Screw-pile
Since the Colonial period, one of the major waterways on the eastern seaboard has been the Delaware Bay and River. The Bay and River, separating New Jersey from Pennsylvania and Delaware, stretches from the mouth all the way to Philadelphia, Camden and Trenton. Prior to the completion of the Ene Canal in 1825, which elevated New York City to a major port, Philadelphia and Boston were the primary seaports of the colonies and our new nation. One of the twelve colonial lighthouses was situated at Cape Henlopen, on the south side of the entrance to the Bay.
