The temple of Bellona is a temple or sacellum dedicated to the Italic goddess Bellona (possibly here syncretised with Magna Mater) in Ostia Antica.
It is to be found on the east side of the "Campo di Magna Mater" (Regio IV, Insula THE, n. 4) and is made up of a small building with cella preceded by two columns and three frontal steps. All, including the columns, is made of brick. The inside of the cella includes a low podium at the back, frescoed walls, a white mosaic floor and a marble threshold with the holes for the door pivots.
In the temple a relief of two pairs of feet was found, facing in opposite directions - perhaps a votive offering by a soldier who had departed for war and returned safely.
