Temple at Arad

Hezekiah became king of Judah in 715 BCE.  He instituted a number of religious reforms.  

2 Kings 18:3-4 records

He (Hezekiah) did what was pleasing to the L-RD, just as his father David had done. He abolished the shrines and smashed the pillars and cut down the sacred post…

Supporting this biblical account, a small sanctuary dating back to the 8th Century BCE was uncovered in the Arad fortress on Judah’s southern border. It is the only Judahite temple ever discovered.  The sanctuary was intentionally buried in the time of King Hezekiah, who sought to abolish all public worship outside the Temple in Jerusalem.
