Civic Buildings

Civic Buildings are a class of structures in Rise of Nations, which are mostly used for expanding your nation's territory, enhancing your economic power, researching various technologies, producing resources and creating civilian units.

Overview

Some Civic Buildings are terrain-limited, and can only be built on resource providing structures, like Mountains, Trees and Oil patches.

A British settlement filled with various Civic Buildings. (Set in the Gunpowder Age)

Other economic structures are city-limited, and only a finite number of them can be built anywhere in each city. While most econonic buildings are restricted to one per city, nations are typically able to build five Farms per city (Egyptians are able to build seven).

Rise of Nations originally had 16 Civic Buildings available to build. The Thrones and Patriots expansion added a Senate building, bringing the total to 17. (There is also Forbidden City, which acts like a Civic Building (Major City), but it's technically a Wonder.)

Some buildings are available from the very beginning, while others can only be built after reaching a specific Age. Additinally, most buildings must be unlocked by researching certain technologies at the Library.

Also, unlocks all technologies at the Temple and Attrition technologies at the Towers. Commerce branch increases the Commerce and  Caravan Limits. Also, unlocks trading at the Market, colonization, and trade routes with other nations. Science branch decreases research cost and time for all technologies, unlocks some civic buildings and their technologies, increases resource bonus from Ruins, and increases the Line of Sight of units and buildings.
