Arelatum - A settlement in Narbonensis also known as Arles
Arelatum was originally a Ligurian settlement, which became an important Phoenician trading port before being taken by the Romans in 123 BC.

After siding with Julius Caesar during the war agains Pompey, it was established as a colony for veterans from Legio VI 'Ferrata' and became an important city.

The mint at Arelatum was opened in AD 313. Early issues use the AR or ARL mintmark. In AD 318 the city was renamed Constantina to mark it as the birthplace of Constantine II. From this time the mintmark CONST or CON was used. After the death of Constantine II in AD 340, the mintmark ARL was reintroduced, lasting until AD 353. After this time it remained CON or CONST.
