Multiple workshops in the same province?

Okay, never tried this yet. But are the bonuses from multiple workshops add to each other? For example I have 3 workshops, which gives 5% armor. Do my new recruits now then gain +15% armor after recruitment?

It doesn't quite work that way as far as I can tell. I run a Blacksmith and a Shieldmaker in my central Italian province. The Blacksmith gives something like Lvl 2 weapons and lvl 1 armor. Conversely, the shield maker gives something like lvl 2 Armor and lvl 2 shields. Both of those things together equal lvl 2 weapons, armor, and shield across the board. While 5% + 10% = 15%, lvl 1 + lvl 2 != Lvl 3.

So the same bonus doesn't stack, but two workshops with different bonuses will give you the highest of each bonus.

Aha! Thanks Red_Barron.

Experience bonuses from germanic groves within the same province stack.

Edit: Also...

Percent-based improvements seem to stack. Tested: Two level 1 bronze workshops in different regions of the same province will indeed give 10% (5+5%) attack to units recruited in the province.

Armor levels, however, might not stack. (Seem to vaguely recall testing this at some earlier time and it did indeed not work.)
