After the destruction, for unknown reasons, of this second temple, a third building was erected in c. 680 B.C., at the same site, using same of the earlier walls. This had three aisles and an early form of tetrastyle portico. This too was short-lived. Around the end of the 7th century B.C., the cult was again carried out in the open-air, the focus being a four-sided clay hearth. It was found practically intact, and it is visible beneath the marble threshold of the later adyton.
