Why did castles have square towers?
The towers on early castles were square until it was realised that incoming projectiles, rocks from catapults and cannon balls did considerable damage where ever they hit the towers. To reduce the damage it was reasoned that round towers would only suffer major damage if struck in the middle. Shot striking off-centre would have some of the force, and hopefully the ball or rock, deflected. This turned out to be the case.
