Which part of the pediment is typically decorated with relief sculptures?

The tympanum is the area of a pediment that is typically decorated with relief sculptures. This triangular space created by the sloping sides of the pediment serves as a prominent focal point in classical architecture, often showcasing significant artistic features such as sculptures that depict mythological scenes, historical events, or symbolic figures.

The relief artworks enhance the visual appeal of the structure and convey narratives or themes pertinent to the building's purpose. In contrast, the architrave, frieze, and cornice have different roles in classical architecture; they serve structural and ornamental purposes but are not typically the primary areas for relief decoration. The tympanum, being in a central and elevated position, effectively draws the viewer's attention and serves as an ideal canvas for such artistic expressions.
