The structure long called the Tombs of the Kings — a monumental rock-cut tomb complex on Sultan Suleiman Street, a few hundred yards north of the Damascus Gate of the Old City of Jerusalem — is in fact the family tomb of Queen Helena of Adiabene, a first-century-AD royal convert to Judaism. The misnomer entered European literature in the medieval and early modern period under the assumption that the scale and ornament of the complex marked it as the lost burial place of the Davidic kings of Judah; the identification was never archaeologically secure and has been recognized as wrong for more than a century. The Davidic kings of Judah were buried in the City of David per 1 Kings 2:10 and the parallel formulae for the Judahite royal succession. Josephus tells the actual story. In Antiquities 20.17–96 he records the conversion of Queen Helena and her son Izates of the small Mesopotamian kingdom of Adiabene, Helena's pilgrimage to Jerusalem around AD 30, her famine-relief gifts to the city during the famine remembered in Acts 11:27–30, her residence in the city through her sons' visits in the AD 40s, and her burial "three stadia distant from the city" in a tomb she had ordered built. She died around AD 56–58. The tomb was acquired by the French explorer and orientalist Félicien de Saulcy in 1863 — making it the only French-owned property in Jerusalem to this day. De Saulcy's excavation recovered the great rolling stone, the antechamber with its stepped descent, and the sarcophagi of the Adiabene royal family. Roland de Vaux re-examined the architecture in the twentieth century and confirmed the Roman-period date and the Adiabene attribution. The tomb is currently French government property, administered by the French Consulate-General in Jerusalem; access has been intermittent across the past half-century and is currently restricted pending conservation work.

Helena's tomb provides the only archaeologically identifiable burial monument connected to figures named in Josephus's detailed conversion narrative, and its famine-relief context intersects directly with Acts 11:27–30. The complex also illustrates first-century Jerusalem's attraction for Diaspora converts at the precise moment of early Christianity's emergence.
