A pediment is a triangular architectural feature that sits atop a building's entrance or window. It is commonly found in classical architecture, particularly in structures like temples and government buildings. The pediment often serves as a decorative element, enhancing the overall aesthetic of the facade. Typically, a pediment is supported by columns and may be adorned with sculptures or reliefs. This design element can be seen in famous structures such as the Parthenon in Athens and the United States Supreme Court building. Pediments can vary in style, from simple and unadorned to highly detailed and ornate.
