Mod «EU4 Style Monuments» for Hearts of Iron 4 (v1.10.1 - 1.10.7)


This mod brings the, slightly changed, monuments mechanic from Europa Universalis IV to Hearts of Iron IV.


Currently the mod adds 107 monuments in total, of which 103 exist on the map at game start. 4 additional monuments can be built via decision, if the requirements are met.

Monuments are special things in states that can give bonuses to the state as well as its owner. Some of them are locked to being one of a group of specific nations or fulfilling other requirements, some are available for all nations if they own and control the state.

Each monument has the four possible levels "Destroyed/Not Build", "Noteworthy", "Significant" and "Magnificent". Each level gives a stronger bonus than the one before, with the level "Destroyed/Not Build" (level 0) giving no bonuses. The owner of a state in which a monument is located can upgrade the monument to a higher level, if he controls the state and fulfills the monument's requirements. Upgrading a monument costs Political Power and takes some time, which cannot be boosted like in EU4.

Monuments can be viewed and interacted with in the state view as well as in a new window, which shows all existing monuments. This window can be opened with a button in the top right of the top bar, left to the date controls.

Since that position can be quite problematic for lower resolutions, there is a console command that can be used in single player to move it elsewhere. The console command is move_monuments_list_button X Y (where X and Y are placeholders for the specific number for the X and Y coordinates, e.g. move_monuments_list_button -50 0 would move it 50 pixels to the left from its default position).

AI nations will also build and upgrade monuments, however to prevent them from investing their Political Power purely into them, they will only consider doing this if they have at least 300 Political Power available.
