Watch tower in city provinces

[north radish]

I really like the watch tower giving more vision, when visited by a unit.
But I think if the watchtower is in one of your city provinces, the visibility bonus should apply regardless of a visiting unit.

Pretty cool idea, to strategically place watch towers for extra vision! the watch tower could act as a small tower, with a wall with siege health of 10... so after 1 turn, the invading army will see 1-2 archers on the battlements, a minor nuisance!

could delay occupying or razing certain province improvements (such as the spell jammer)... outside the city, the spell jammer province could be defended with some archers and 10hp fortification health (if it would be possible to add a watch defensive tower on the same province as a special province improvement!)

maybe several types of towers:

1. watch tower (vision, 10 forti health)
2. ballista/magic damage tower (less vision, 20forti health)
3. summon random undead tower...

the possibilities are endless

I hope somebody mods this in! 😄

So basically these towers with fortification health would defend certain significant special provinces from being razed/pillaged/occupied!
