What are Province Buildings and which benefits do they bring?

On the Battleground map, each province can have from 1 to 3 slots on which buildings can be constructed. Anyone can donate goods to the guild treasury to help pay the costs, but only members with a special guild role (“battleground constructor”) can raise buildings on provinces owned by their guild. Every ‘founder’ and ‘leader’ of a guild will automatically have this role as well.
Only the eras that are represented in a guild will determine the costs of province buildings (treasury goods). These province buildings have a building time, and it’s possible to cancel or remove a construction at any time to free the slot for another building. In such a case, spent resources are not returned to the treasury.
When a province gets conquered by another guild, every building (including the ones under construction) has a chance of 50% to be destroyed, and the remaining ones will benefit the new owner. There are 9 different strategical buildings available, so make sure you choose them wisely.

Decoys, Traps and Watchtowers
Three original GbG buildings. If your enemies fight/negotiate in a province with either traps or decoys, there's a chance that they will suffer double the amount of attrition.

Building	Name	Properties	Location	Costs	Construction Time	Instant Construction price
	Decoys	If an enemy fights or negotiates to conquer this province, there is a chance of 15% that this enemy will suffer double the amount of attrition.	Any empty slot, excluding starting province	500	4:00:00	50
	Traps	If an enemy fights or negotiates to conquer this province, there is a chance of 45% that this enemy will suffer double the amount of attrition.	Any empty slot, excluding starting province	3,000	5:00:00	50
	Watchtower	If members of the owning guild of this province advance into adjacent provinces, they have a 8% chance to not increase their attrition level.	Any empty slot, excluding starting province	500	1:00:00	50

Fieldcamps
These buildings can only be build in your Guild starting province and provide 26-80% chance reduction to gain attrition (only adjacent provinces). All provinces generate 25-100% more victory points. Every Guild starting province will have just one building slot.

The Guild Starting province can not be conquered by other guilds.

Barracks
These buildings can be build on any empty slot, excluding starting province and provide 20-60% chance reduction to gain attrition (only adjacent provinces). The province also requires 5-30% more advances to be conquered
