Scholarly reconstruction
Solomonic (high chronology)
The gates are 10th-century and fit 1 Kings 9:15 (Yadin, Dever).
Ancient Mysteries & Interpretations
Yigael Yadin connected similar six-chambered gates at Hazor, Megiddo and Gezer with 1 Kings 9:15. The "low chronology" redates them to the 9th century BC, the time of Omri and Ahab. Radiocarbon studies (including Tel Rehov) have narrowed the debate but not ended it. The gates are real; their builder is disputed.

"…to build… Hazor, and Megiddo, and Gezer" (1 Kings 9:15).
Yadin found the Hazor gate in the 1950s and recognized the same plan in Megiddo (excavated by the Chicago expedition) and in a gate at Gezer identified in earlier reports. Later excavations at Megiddo (Finkelstein, Ussishkin, Halpern) and Gezer (Dever; Ortiz and Wolff) re-examined the stratigraphy.

Six-chambered gates were built at major royal cities in the 10th or 9th century BC. Whether Solomon built them depends on dating debates that remain open.
