Historical Irrigation Systems
This mod adds an "irrigation building" to regions where it is appropriate, and which I think has been made too weak, due to low barony count, but which were significantly more wealthy and powerfully in real history.
Various tiers of irrigation special building are placed in Egypt, Mesopotamia, and in India; I based them on vanilla windmills, but irrigation ones are available early game.
You can upgrade those buildings depending on regions potential (displayed as county modifier).
I’ve also added a "Lighthouse of Alexandria" for… well… Alexandria…
