Now at In situ, City of David archaeological park (open to visitors)
How Warren's Shaft was found
Exploring the cave of the Gihon Spring, Warren noticed a vertical shaft rising from the tunnel and climbed it, finding a sloping passage that led up into the city. Reich and Shukron's excavations in the 1990s–2000s showed the shaft was a natural fissure that the original tunnel-cutters bypassed.
What it is
A natural karstic shaft about 13 m deep connecting a stepped, rock-cut tunnel from inside the city with the level of the spring. The tunnel let people walk down under the wall toward the spring and its pool without going outside.
Why it matters for the Bible
For a century Warren's Shaft was the favorite explanation of the 'tsinnor' through which Yoav (Joab) supposedly entered Jerusalem when David captured it. The modern excavations showed the shaft's bottom was not even open in David's time, so that neat identification no longer works. The tunnel system itself, however, is real and old, and proves the Jebusite city had a protected way to its water, the kind of feature the Bible's story assumes. It remains the first and most famous piece of Jerusalem's water engineering to be found by modern exploration.
The Hebrew word: tzee-NOHR
צִנּוֹר
צִנּוֹר is pronounced tzee-NOHR and means water channel, shaft (2 Samuel 5:8) — a rare word whose meaning is debated (Strong's H6794).
