Kenyon found the walls had fallen outward, creating a ramp of debris that an attacker could climb. Sieges push walls inward. Something else happened at Jericho.
Tell es-Sultan sits in the Jordan Valley near modern Jericho, roughly 250 meters below sea level. It is one of the most excavated sites in the Levant, and one of the most contested. What archaeologists found there matches the strange details of a story in Joshua 6.
Kenyon’s excavation (1952-1958)
Dame Kathleen Kenyon of the British School of Archaeology in Jerusalem conducted the most rigorous excavation of Jericho between 1952 and 1958, employing the Wheeler-Kenyon stratigraphic method. Her findings, published in Excavations at Jericho (Vols. I-V, 1960-1983), documented three key features.
First, the mudbrick walls of City IV had collapsed outward, falling down the slope of the tell and forming a ramp of debris at the base. Siege warfare typically pushes walls inward — battering rams and sappers cause walls to buckle toward the interior. Walls that fall outward suggest a sudden catastrophic force: earthquake, undermining, or some combination.
Second, a thick layer of ash covered the destruction level, indicating the city was burned after the walls fell. Joshua 6:24 states that “they burned the whole city and everything in it.”
Third — and most puzzling — the storerooms contained large quantities of grain. Kenyon’s team found dozens of storage jars still full of carbonized wheat and barley. In ancient warfare, grain was the prize. A besieging army would first exhaust a city’s food supply, then plunder the stores after breach. Full granaries suggest the city fell quickly and the conquerors did not take the food.
The dating controversy
Kenyon dated the destruction to approximately 1550 BCE, based on the absence of imported Cypriot bichrome ware. This placed it a century before any plausible Israelite conquest, and she attributed it to the Egyptian expulsion of the Hyksos.
In 1990, Bryant G. Wood — publishing in Biblical Archaeology Review (March/April 1990) — challenged Kenyon’s dating. Wood argued she had relied on absence of evidence rather than presence. He pointed to locally made bichrome ware, Egyptian scarabs datable to the 18th Dynasty, and radiocarbon dates clustering around 1400 BCE (plus or minus 50 years), aligning with the conventional early date for the Israelite entry into Canaan.
Radiocarbon testing by Hendrik J. Bruins and Johannes van der Plicht, published in Nature (1995, Vol. 382), produced a date range of 1410-1340 BCE from grain samples in the destruction layer. Piotr Bienkowski, in a 1990 response in the Palestine Exploration Quarterly, defended Kenyon’s chronology. The debate remains unresolved, with both positions holding peer-reviewed support.
What the evidence does and does not prove
The archaeology at Tell es-Sultan confirms several specific claims in Joshua 6: the city had walls, the walls fell outward, the city was burned, and the grain was not looted. The text adds that Israel was commanded not to take plunder (Joshua 6:18-19) — an unusual instruction that would explain intact grain stores.
What the evidence cannot confirm is the mechanism. Joshua describes ritual procession, trumpet blasts, and divine intervention. Archaeology records the result — sudden collapse, fire, untouched grain — but cannot adjudicate between natural catastrophe (the Jordan Rift Valley is seismically active) and supernatural cause.
The date remains the critical variable. If Wood and the radiocarbon evidence are correct at approximately 1400 BCE, the match is remarkably precise. If Kenyon’s ceramic chronology holds at 1550 BCE, the connection dissolves.
Either way, someone’s walls fell outward, and no one touched the grain. That much is in the ground.
