I just dont' get it

When you conquer a province, it says:
buildings damaged: x
building destroyed: x
On what base does the game decide how many buildings will be damaged/destroyed?
Last night, I invaded Castille(a province with nice set of buildings).During the battle I don't recall damaging any of the buildings on the map.However,when the battle finished,I got this (annoying)message:
buildings destroyed: 10

I just don't get it.
In R:TW there will be a possibility of deciding what and how much will a building be damaged,so I look forward to it http://www.totalwar.org/forum/non-cgi/emoticons/cool.gif

Youp, that´s not nice.. And I´m sure that we all now how bad AI is to upgrade provinces. That doesn´t offer much challenge when enemy can´t create a good infrastructure even at peacetimes, and lost its few buildings at war.. http://www.totalwar.org/forum/non-cgi/emoticons/mad.gif

Those buildings at battlefield has nothing to do with the provinces buildings.. I guess.

I think (I've got nothing to back this up mind you) the destruction of the buildings after a battle takes place when your successful troops sack the town. It happened a lot during the period, basically the winning side would run into the town, have a big party (much rape and pillage) and there was very little the commanders could do about it.

The destruction/damaging is random. The higher the level of the castle, the lower the chance of this happening.

btw religious buildings are automatically destroyed,if your playing a faction with a different religion than the faction your fighting.

I think that the system has change a little after VI. There is now usually a very little destroyed buildings when you take control of the province from enemy, but siege isn´t end yet. It seems that if you decide to assault the castle, there is less buildings lost, but castle´s upgrade level drops by one (Castle becomes Keep). If just besiege and wait it to fell, castle would not suffer, but more buildings will be lost..
