Discovery of a 300-meter Section of Jerusalem’s Lower Aqueduct

Discovery and Immediate Context
Archaeologists from the Israel Antiquities Authority (IAA) uncovered a 300-meter stretch of the ancient Lower Aqueduct during salvage work for a planned residential development south of Kibbutz Ramat Rachel, near Jerusalem. Directed by Dr. Benyamin Storchan and Gil Freid, the excavation revealed the stone-lined channel and surrounding plaster that had been buried for centuries. The find was announced on Sunday, prompting coordination with the Israel Land Authority (ILA) to protect the structure.
Historical Background of the Lower Aqueduct
The aqueduct dates to the Hasmonean period (late 2nd to early 1st century B.C.E.) and was designed to convey spring water from the Gush Etzion highlands to Solomon’s Pools, then onward to the Temple Mount. IAA officials estimate the system originally spanned roughly 21 km; Haaretz reports about 26 km. The route followed a gentle gradient, descending approximately one meter per kilometer.
Engineering Features and Longevity
The Lower Aqueduct combined a plaster-lined channel with later Ottoman-era ceramic pipes inserted within the original conduit. Stone pebbles were pressed into the external plaster while wet, creating a textured surface that persists along the exposed section. The gradient allowed water to flow solely by gravity. Repair marks from Roman, Byzantine, Umayyad, Crusader, Mamluk and Ottoman periods demonstrate use for more than two millennia. The aqueduct remained functional until roughly a century ago, when modern electric pumping systems replaced it.
Preservation Plans and Urban Development
The ILA and IAA intend to preserve the newly exposed segment as a public archaeological park integrated into the entrance of the forthcoming neighborhood. Officials describe the project as a “continuous park” that will let visitors walk alongside the aqueduct from southern Jerusalem to the Old City.
Official Statements & Responses
Dr. Amit Re’em, the IAA’s Jerusalem district archaeologist, called the aqueduct “an engineering marvel” whose construction would demand extensive planning even with today’s technology. Municipal planners said the neighborhood layout will be adjusted to keep the ancient structure visible and accessible.
Data & Statistics
- Length of aqueduct: reported as 21 km (IAA) and 26 km.
- Gradient: one meter drop per kilometer.
- Exposed segment: 300 meters (? 985 feet).
- Construction period: Hasmonean era, late 2nd–early 1st century B.C.E.
- Duration of use: over 2,000 years, intermittently until the early 20th century.
Conflicting Reports & Gaps
Sources differ on the total length, with the IAA citing 21 km and Haaretz describing 26 km. Precise dating remains uncertain because successive repairs have layered plaster and mortar from multiple periods, complicating stratigraphic analysis. Researchers plan to apply optically stimulated luminescence and mortar analysis to refine the chronology, but definitive dates have not yet been established.

- “The magnificent discovery of the ancient aqueduct in the heart of the area planned for Jerusalem's new neighborhood reminds us that we are continuing a proud legacy of construction and development spanning generations.” — The IAA
What’s Next
The archaeological park and neighborhood entrance integration are slated to proceed alongside the development’s construction timeline.
