Archaeologists have long known of the existence of the Acra fortress, used by forces loyal to Antiochus Epiphanes during the Maccabean revolt, but have been unable to locate it. A group of Israeli archaeologists believe they have done so (although some disagree). The Times of Israel reports:
[T]he Israel Antiquities Authority announced Tuesday that they have found the remnants of a fortress used by the Seleucid Greek king Antiochus Epiphanes in his siege of Jerusalem in 168 BCE.
A section of fortification was discovered under the Givati parking lot in the City of David south of the Old City walls and the Temple Mount. . . . Antiochus is remembered in the Jewish tradition as the villain of the Hanukkah holiday who sought to ban Jewish religious rites, sparking the Maccabean revolt.
The Acra fortress was used by his Seleucids to oversee the Temple and maintain control over Jerusalem. The fortress was manned by Hellenized Jews, who many scholars believe were then engaged in a full-fledged civil war with traditionalist Jews represented by the Maccabees. Mercenaries paid by Antiochus rounded out the force.
The discovery of the Acra’s foundations ends over a century of intense speculation over its location. . . . The fortress is mentioned in the first and second books of Maccabees, and by the Roman-era Jewish historian Josephus.
