An arch is an opening in a building that is curved on top that distributes the weight . The curved part can be round, like part of a circle, or pointed, like two parts of circles next to each other. Arches are often used where buildings are made of lots of small stones or bricks. The stone at the very top of the arch, called the keystone, keeps the rest of the arch stones from falling down. arches can go over doorways and windows. Many bridges are arch bridges. A series of arches is an arcade.
