Rutupiæ was the Roman name for Richborough near Sandwich, Kent, which they founded after they landed in England in AD 43. A major port of Roman Britain (with Dubris, it was one of the start-points for the Roman road of Watling Street, which ran on to Canterbury and London), it has many phases of Roman remains, collectively known as Richborough Fort or Richborough Roman Fort, still visible today and under the care of English Heritage. (A third, local name, Richborough Castle, is used mainly just for the Saxon Shore Fort walls.) Earth fortifications were first dug on the site in the 1st century, probably was as a storage depot and bridgehead for the Roman army. This transformed into a civilian and commercial town, which was later replaced by a Saxon Shore Fort around the year 277. The later fort is believed to have been constructed by Carausius.
