Summary
Duchy Buildings are a great way to reap the rewards of controlling an entire Duchy. In order to do this, players must first own every De Jure territory within a given Duchy, after which a new building option will appear in the De Jure Capital. Some cities will already have certain Special Buildings built into them, such as the Walls of Genoa or the Colosseum in Rome, and others will be able to construct Universities once a certain level ofCultural knowledgeis achieved.
However, Duchy Buildings enable the player to choose from a large variety of options, with each providing significant bonuses to a different sector of management. Some buildings may provide helpful increases to tax collection, while others can helpbolster military powerand make hunting success more likely. It is worth noting that players will only be able to choose the buildings they wish to construct in personally owned territories and won’t be able to change vassal’s constructions without first revoking their rights.
