Question

Why is the pointed arch seen in Gothic architecture structurally more stable than the rounded arch used earlier

Answer 1

it directed weight downward into the ground rather than outward onto the wall.

Answer 2

It allowed for taller and lighter structures to be built.

Step-by-step explanation:

With pointed arches, walls can be higher and thinner since the two sides of the walls are leaning on each other; for support and thus the weight are directed downwards, offering more stability. Also the Gothic style allowed for taller buildings as opposed to a rounded arch.

It also allowed for more flamboyant decoration as a result of the higher and thinner ceilings.
