Ironmine

General Information
The Ironmine produces Iron, which is used for construction and research and is also used to upgrade weapons and armors.

History
The massive use of Iron may date back to circa 1,000 BC. The continuous demand for Iron led to the development of Iron Mining.

Upgrades

 * Note that construction of Level 10 Ironmine also requires one unit of Michelangelo's Script
 * Note that Levels above 10 can only be built in a Historical City(incomplete page), but do not require an additional Michelangelo's Script once Level 10 is reached.
