no parapets or bartizans any more. Just flat walls
Most fortified towers have tiny, almost non-existent windows - this was for defensive purposes, of course. Arrow slits, and later gun ports, allowed for coverage of the walls (although the more common L-plan or Z-plans with round towers on the corners allowed defenders to fire along the walls, not just out from them.
