Because of the religious and political sensitivities involved, no archaeological excavations and only limited surface surveys of the Temple Mount have been conducted since Charles Warren's expedition of 1867-70. There is no archaeological evidence for the existence of Solomon's Temple, and the building is not mentioned in surviving extra-biblical accounts. Israel Finkelstein and Neil Asher Silberman argue that the first Jewish temple in Jerusalem was not built until the end of the 7th century BCE, around three hundred years after Solomon. They believe the temple should not really be assigned to Solomon, who they see as little more than a small-time hill country chieftain, and argue that it was most likely built by Josiah, who governed Judah from 639 to 609 BCE.
