This 23-foot-thick city wall was built in 701 BC under King Hezekiah of Judah as an urgent defense against the Assyrian invasion led by Sennacherib. Its massive stone construction reflects Jerusalem’s strategic importance and confirms the historical reality behind the Old Testament. For modern visitors, especially Americans, the wall transforms ancient Scripture into tangible history, connecting today’s world to the foundations of faith, leadership, and identity shaped here nearly 2,700 years ago.
