Buildings

Various city upgrades can be erected in the City Upgrades Tab. They cost a one-time amount of gold and wood as well as a weekly upkeep cost (gold).

Strategy

 * Building construction can be paused. Pausing construction can be useful if you have limited wood and you want to prioritize a different construction project.
 * Constructing upgrade buildings in cities or camps is much faster if the wood is already stockpiled locally. Use the stockpile control in the trade tab to move wood before construction begins.
 * Don't forget watchtowers, they can be very useful in providing advanced warning of an enemy attack giving you time to move units into the area.
