A dome is a curved structural element resembling the upper half of a sphere. It is an efficient way to enclose a large space without internal supports. It distributes weight evenly, making it very strong. Domes have been used in architecture for thousands of years. It's a symbol of power and grandeur. Think of it as a 3D arch that rotates 360 degrees. They vary in shape from semi-spherical to elliptical.
