The Casa de Contratación is a Renaissance Era Wonder in Civilization VI: Rise and Fall. It must be built adjacent to a Government Plaza.
- Effects:
- +3 Great Merchant points per turn
- Gain 3 Governor promotions.
- All your cities on your non-home continent with a Governor gain +15% Production, +15% Faith and +15% Gold.
Strategy
The perfect wonder for intercontinental empires, the Casa de Contratación is a great fit for civs who wish to expand to all continents such as England and Spain. Phoenicians can easily abuse this wonder with their Move Capital special project, turning your "original" cities into powerhouses. The boosts granted to non-home continent cities can be further boosted by policy cards such as Colonial Taxes and Colonial Offices. Even if one does not have any cities on foreign continents, the wonder may still be worth building due to its granting of Great Merchant points and otherwise-scarce Governor Titles.
Civilopedia entry
When Spain joined the late 15th Century’s exploration race, Queen Isabella I of Castile and Ferdinand II of Aragón realized they needed a firmer grasp on colonial trade and expansion. Through their Casa de Contratación, a “House of Trade” created to regulate trade and procurement, the Spanish crown controlled everything related to trade and sea travel down to the smallest details. Even their navigation and cartography school kept literal trade secrets in house.
Seville was home to the first incarnation of the Casa de Contración, but the agency moved to Cádiz in 1717. Moving to a city near the southern tip of Spain streamlined the influx of ships, which had previously traveled up the highly trafficked Guadalquivir River. The Casa remained in Cádiz until its termination in 1790 due to the empire’s growing debts.
