Here, after reconnoitering the stream, Minuit met with Indians and purchased lands from Duck Creek (the southern boundary of New Castle County) to the Schuylkill. Here too a site was picked for a settlement that was called Fort Christina. It was at the Rocks, ‘a wharf of stone’ on the Christina about two miles from the Delaware River and above the junction of the Christina and its main tributary, the Brandywine, on the east side of the present city of Wilmington.”
