Located on the south bank of the Thames Estuary, Gravesend is a town in Kent that has held important maritime significance. Archaeological evidence suggests that Gravesend has existed since the Iron Age, and many Roman ruins have been excavated. It has long been used as a landing place and a shipping port, particularly because of the river Thames and access to London via water. The Port of London Authority Control Center’s headquarters is located in Gravesend. The Native American chieftain’s daughter, Pocahontas died in Gravesend and was buried at St. George parish church.
