A metope (/ˈmɛtəpi/; Ancient Greek: μετόπη) is a rectangular architectural element of the Doric order, filling the space between triglyphs in a frieze, a decorative band above an architrave.In earlier wooden buildings the spaces between triglyphs were first open, and later the free spaces in between triglyphs were closed with metopes; however, metopes are not load-bearing part of a building.Earlier metopes are plain, but later metopes were painted or ornamented with reliefs. The painting on most metopes has been lost, but sufficient traces remain to allow a close idea of their original appearance.
In terms of structure, metopes were made out of clay or stone. A stone metope may be carved from a single block with a triglyph (or triglyphs), or they may be cut separately and slide into slots in the triglyph blocks as at the Temple of Aphaea. Sometimes the metopes and friezes were cut from different stone, so as to provide color contrast. Although they tend to be close to square in shape, some metopes are noticeably larger in height or in width. They may also vary in width within a single structure to allow for corner contraction, an adjustment of the column spacing and arrangement of the Doric frieze in a temple to make the design appear more harmonious.
