Fortifications

Apart from regular buildings, it's possible to build wall fortifications (city walls). Their main goal is to improve the city's defenses [not yet implemented]. What's more, building any fortification increases the cities borders up to 2 regions (which might increase the area where peasants can work if villages are built). Several advanced buildings require fortifications to be built.

Better types fortifications provide more defense bonus and points., but they need more resources and construction time. A full list of wall types is available here.

Walls are built the same like regular buildings; it requires construction materials and builders. The difference is that you can upgrade walls - build better ones without demolishing the old one. You can do that by clicking the wall and selecting “Upgrade wall”.

The building details dialog for the wall will show the upgrade in progress.
