Novus Portus - 'The New Port'

The only classical evidence for a Roman port and settlement on the south coast near Brighton is an entry in Ptolemy's Geography of the second century AD. After the entries for Chichester and the mouth of the River Arun in Sussex, and before the South Foreland in Kent there appears the entry Novus Portus, which, from its given position would appear to be somewhere in the region of Brighton and Hove, perhaps near the mouth of the River Adur near Portslade-by-Sea.

"Description of the south side below which is the Oceanus Britannicus ... Magnus Portus 19*00 53� ¹ ost. Trisantonis Fl. 20*20 53� ² Novus Portus 21*00 53� Cantium Prom. 22*00 54� ³ ..."
Above extract from the Geography of Claudius Ptolemaeus
  1. Identified as Chichester, Sussex; know as Noviomagus.
  2. Very likely the River Arun in Sussex.
  3. Undoubtedly the South Foreland of Kent.

The Roman road from London continues beyond Hassocks towards the south coast at Brighton, where numerous Roman finds have been made. There is a fairly high probability of there being a Roman settlement either hidden under the streets of the modern town, or else built further to the south, and now forever lost to the eroding effects of the Oceanus Britannicus.

Other Roman Sites in the Area

The remains of three Roman villas are known in the immediate locale; at Southwick (TQ2405), West Blatchington (TQ2707) and Preston (TQ3005). A Roman milestone found further west along the coast at Worthing (TQ1302) probably points to there being a coastal road-link to Noviomagus (Chichester), which also served the villas at Angmering (TQ0504) and Littlehampton (TQ0302). There is a Shrine or Temple a few miles to the west at Lancing Ring (TQ1706), two others at Chanctonbury Ring (TQ1312) and another at Findon (TQ1009).
