As the Greek Empire fell into decline, the Romans stepped in to
take control of the Mediterranean region. By the 2nd century BC,
Rome had developed the southern region of France into one of its
provinces and began incorporating the small towns into its empire.

In 43 BC, Antibes (or Antipolis, as it was then called) was officially
annexed by Rome and remained so for the next 500 years. The Romans turned
Antipolis into the biggest town in the region and a main entry point into Gaul.
Roman artefacts such as aqueducts, fortified walls and amphora can still be seen today.
