 Before 1911, Richborough Port was known as "Sandwich Haven".There was a gravel pit (now a lake) and a quay on the Long Reach of the River Stour, used during the construction of the Admiralty Harbour at Dover by S. Pearson & Sons Co.This firm built a tramway, nicknamed "Pearson's Railway", from a junction with the SECR at Richborough Castle to the pit and to "Pierson's Quay" (also known as "Old Quay" or "Stonor Quay").
