Catapult question

Can anyone tell me with reasonable certainty how many catapults it takes to take down an Academy and Church? Thanks.

When you do discover the number, keep in mind that the battle % still plays a role(the modifier included with your battle report), and that catapults do not launch rocks at buildings until after combat. I know a church takes upwards of 500-700.
