What possible physical evidence has been found to confirm hezekiah's reform?

The Tunnel

Explanation:

Hezekiah led a monotheistic religious reform against idolatry that strived to unify the worship of Yahweh in Jerusalem.  

An extraordinary engineering achievement was the 533 meters long tunnel dug to give Jerusalem subterrene access to the Spring of Gihon, located outside of the city.  

The large wall located in the Jewish Quarter of the Old City of Jerusalem was considered as physical evidence of that structure existence.
