What are Arches?

An arch is a curved structure that is used to support the weight of a bridge, doorway, or other architectural element. Arches are made up of individual blocks or stones, called voussoirs, that are held together by the force of gravity and the shape of the curve. Arches have been used in architecture for thousands of years and are known for their strength and stability.

Types of Arches

There are several different types of arches, including:

• Round arch: This is the most common type of arch, with a semicircular shape.
• Pointed arch: Also known as a Gothic arch, this type has a pointed or angular shape.
• Flat arch: This type has a wider, flatter curve and is often used in buildings with lower ceilings.
• Horseshoe arch: This type has a rounded top and is often associated with Moorish architecture.

How Arches Work

Arches work by transferring the weight of the structure above them outward and downward along the curve of the arch. This allows the weight to be distributed to the supporting columns or walls on either side of the arch, creating a stable and strong support system.
