Gold
Gold is the main currency of Nova Roma, used to pay wages to specialized workers, recruit military units, and build advanced buildings, as well as execute Terrain Engineering projects.
Gold is gathered from 
Citizens via Taxes by Tax Collectors. Tax Collectors are employed by Tax Office buildings.
Collected gold is stored in Temples, ranging from 200 in a Small Temple to 500 in a Large Temple.
Taxes
The tax office is an important building in Nova Roma, being your only way to collect gold which is essential for many buildings. The higher the tax rate, the less happy your citizens will be in its radius. There are 7 tax rates, 0%, 10%, 20%, 30%, 40%, 50%, 60% which are collected in an eleven tile radius from the side of the tax office.
The tax office produces different amounts of money depending on which kind of residence it is and how high the tax rate is. At 10% tax the Hovel will produce 3.2x gold for every hovel, eg. 3.2x6. At 10% tax the Small Insula will produce 8x gold for every Small Insula. At 10% tax the Villa Rustica will produce 6.4x gold for every Villa Rustica.
