River Ports
River Ports are important in the development of trade transport and communication.
River Ports played an important role in the economy of the ancient world. Most of the important fluvial ways of today were used just as heavily in ancient times and enabled the transport of valuable and numerous tradable goods, from food to tin.

Inland Trade centre
A Merchants' District is the commercial hub of many provinces. Anything imaginable is available to a man with gold in his purse. Artisans, carpenters, wheelmakers, and innkeepers all ply their trades here. Workshops employed both citizens and slaves. Artisans formed guilds and collectively improved their area.
The growth of fluvial trade led the Romans to improve their infrastructure. The inlands ports became very elaborated and were included in some oppida. Centred on a great jetty, the most important were place under the blessing of the divinities, who were later symbolized with big statues, like in Geneva. Moreover, this development also led to the establishment of a complete customs system all along the rivers.
