History of Petersburg, Virginia
Petersburg was founded and settled by English colonists. By 1635 they had patented land along the south bank of the Appomattox River as far west as present-day Sycamore Street, and about inland. In 1646, the Virginia Colony established Fort Henry a short distance from the Appamatuck town, near the falls. Col. Abraham Wood sent several famous expeditions out from here in the following years to explore points to the west, as far as the Appalachian Mountains.
