Part of the entablature from the corner of one of the smaller archaic buildings on the Acropolis, preserved fragmentarily. It possibly belongs to the same building as the "Olive Pediment", Ακρ. 52. The entablature’s members, such as the architrave, triglyphs, metopes, and cornice are made of poros limestone, whereas the roof-gutter out of marble.

The part of the architrave that survives has an oblong band in its upper edge and small regulae. Each regula is decorated with five cylindrical guttae (drops), probably imitating nails. The triglyphs are alternating with the metopes which are decorated with scenes either painted or rendered in relief. Over the zone of the triglyphs and metopes the protruding cornice, with the promochthoi on its underside, bears traces of painted decoration. The roof-gutter, made of marble, also preserves traces of similar decoration.
