Forbidden Palace and corruption

[lewriczin]

Does it count only for the city it's been build or does it influence nearby cities as well?

The nearby cities will also work with it as the city with Forbidden Palace will be counted as second capital. So better build it at another center city far away from your capital.

Well, according to some sources it worked that way at the begining, but in conquest (the version we have here on steam) they changed (nerfed) it to be the local thing only. So still preferable to build somewhere away, but only for that one particular city.

Ok, Forbidden Palace does have an impact to the nearest cities too even in Conquest.
It's not too big however, and I definitely wouldn't call it as big as second capital but it's something.

best ways to nerf corruption is to have capitols, Forbidden Palace, secret police of equivalent spread across your territory and Communism doesn't hurt either.

I recently learned that the precise formula can be found at https://forums.civfanatics.com/threads/everything-about-corruption-c3c-edition.76619/

Key takeaways, assuming we don't use Communism:

0. There are two factors for corruption/waste and the two added together is the actual corruption/waste.

1. The first factor depends on the distance to the Palace or the Forbidden Palace, whichever is smaller, so Forbidden Palace reduces this factor for all nearby cities.

2. The second factor depends on the distance to the Palace, not the Forbidden Palace.
(More precisely, it depends on the rank of this distance.)
However, the presence of Forbidden palace gives a global reduction to this second factor; this noticeably affect all cities in the realm except for the capital who doesn't care. (I think it's about 30-40% of this second factor, and maybe typically 10%-20% to the actual corruption/waste?)

3. An exception: the city that has Forbidden Palace has its corruption capped at 20%, or 10% with courthouse or police station, or 0% with both. Pretty often that's a drastic change.
