The Dome is a large, architectural structure characterized by its rounded roof, often found in various buildings such as churches, government buildings, and sports arenas. It serves both aesthetic and functional purposes, providing a spacious interior while allowing natural light to enter. Famous examples include the Pantheon in Rome and the United States Capitol in Washington, D.C. Dome construction can utilize various materials, including concrete, steel, and glass. The design often incorporates a central opening, known as an oculus, which can enhance ventilation and illumination. Domes are celebrated for their strength and ability to span large areas without the need for internal supports.
