Extra Duchy Capital Buildings

The mod supports both Chinese and English.


This mod provides more duchy capital buildings to build. It can be roughly divided into two categories: the early duchy architecture and the duchy miraculous architecture.


In the early period of the game, the early duchy architectures can be built in the tribal period, which can only be upgraded to level 2, which plays a transitional role in the early and middle stages of the game. It includes the following buildings:

Ancestral God altar (requires ancestor worship or reincarnation doctrine);

Town Center (it requires technology city planning);

Oracle house;

Royal treasure house (it can be upgraded to miracle building later);

Family Council (it requires technology gavelkind);

Tribal guard (it requires technology bannus);

Mystwood valley (requires anatural primitivism, sanctity of nature or pastoral isolation doctrine)

Holy Legion (it requires technology bannus, and the lord's faith accepts homosexuality)

Battle supervisor (it requires technology bannus)

Nadam assembly (it needs technology compound bows, that is, only nomadic civilizations can build it)

Desert caravan (it needs technology war camels, that is, only desert civilizations can build it)

Snowfield monument (need technology forest wardens, that is, only northeast European and Siberian cultures can build);

Explorer camp



The duchy miraculous architecture generally needs the technology of the middle ages. It can be upgraded to grade 8, which costs a lot, but the cost-effectiveness is still to be discussed (after all, the spectacle destroys the country). It includes the following buildings:

The new tower of Babel (requiring technology windmill);

Trade Center (requiring technology guild);

"Fairy tale" Castle (requiring technology castle baileys);

Mystic spire (no technology required, but build and work requires the Lord to be a wizard or a wise man);

Central port (requiring technology armilary sphere, and of course it should be built by the sea);

Royal workshop (requiring technology windmill);

City inlaid in mountains(requiring technology urbanization, and it should be built on hills or mountains)

Bloody Court (it requires innovation royal prerogative, and build and work require one of the following traits: callous, paranoid, sadistic, arbitrary)

Parliament Palace (it requires innovation divine right, and the development of the territory should not be less than 20)

Military research institute（it requires innovation men at arms）

Imperial communique (it requires innovation urbanization)


Now some duchy miraculous architectures can be upgraded to level 9, and their functions will be more powerful and irreplaceable, but they have additional construction requirements: they generally need the technology of the late Middle Ages, or they have special requirements for the ability and wealth of the builders.



PS: does not support achievement. Mods should be compatible as long as technology tree is not changed.
