City Hall

From the City Hall, you may issue Tax Adjustments, Citizen Pacifications and Citizen Squeezes. Each time you upgrade the City Hall to a higher level, your governing powers increase; you may seize 1 more resource field outside of the city and 3 more production fields within the city, as well as increase the cap on your gold reserves.
