Answer
Brief Explanations:
A flying buttress is an architectural structure that transfers the lateral forces from a wall to an external pier, providing horizontal strength to the wall. It was commonly used during the Gothic period but its main function is to strengthen walls, not just to build large - structures. It is an external support, not an internal column support system.
