Increase your settlements income with the addition of the trader structure and its subsequent enhancements. To gain the most from your trader structure, you should also construct roads, paved roads, and highways as availability arises. The trade structures also provide a small boost to your settlements population growth. The forum, available at the minor city level, also enables the recruitment of the assassin, which can be used to terminate enemy (or even ally) leaders in armies or towns as well as wandering diplomats. Note also that trade structures are the prerequisites for other buildings, such as blacksmiths, health, academies, and amphitheaters.

The weapons-line of structures enhances your melee, cavalry, and ranged units weaponry and armor. After adding a blacksmith, armourer, or foundry to your settlement, retrain present soldiers to receive the enhanced weapons and armor. Your settlement must have a trader to build a blacksmith; a market to build an armourer; and a great forum to build a foundry.

The naval structures offer two primary benefits. Build the port, shipwright, and dockyard to enable the training of naval units, the bireme, trireme, and quinquireme. Utilize your naval fleet to protect your ports and trade lanes and, conversely, to disrupt your enemys (or allys) ports and trade lanes. Blockading an adversarys port can significantly reduce the affected citys income. But the naval structures are also essential to generate income via sea trade. Each new naval structure increases the number of trade fleets available from that settlement. Upgrade each settlement in the trade route to maximize income for each of those settlements.
|Port||Large Town||Provides trade fleets available: 1; enables training of bireme.|
|Shipwright||Minor City||Provides trade fleets available: 2; enables training of trireme.|
|Dockyard||Large City||Provides trade fleets available: 3; enables training of quinquireme.|
The public health structures, as you might expect, help keep your citizens healthy.
