Canaanite and Israelite walls on Jerusalem's eastern hill
The well-preserved wall at the middle level here is late Iron-age (8th century BCE?) and may be the 'broad wall' built by Hezekiah to strengthen Jerusalem's defenses as Sennacherib's Assyrian army approached.
The low remains of another wall in front (at bottom) are Bronze Age remains of the Canaanite city.
The two top tiers of walls (upper left) are modern retaining walls.
