Gravesend is located at a point where the higher land – the lowest point of the dip slope of the North Downs – reaches the Thames. To the east are the low-lying Shorne Marshes; to the west, beyond Northfleet and the Swanscombe Marshes. The settlement was thus established as it was a good landing place: it was also sheltered by the prominent height of what is now called Windmill Hill (see Landmarks below); although Windmill Hill still remains a dominant feature, Gravesend's highest point is actually further inland at Marling Cross, adjacent to the A2.
