Uzziah fixed the damage to Jerusalem's walls caused by Jehoash during his attack on Amaziah. Uzziah might have also repaired damage from the famous earthquake of his time (Amos 1:1; Zechariah 14:5). Towers and cisterns found in excavations at Qumran, Gibeah, Beersheba, and other sites date back to this period.
Uzziah supported agriculture, which was crucial for an independent society.
