What city contained the Antonia Fortress?
The Acra was not the first Hellenistic stronghold in Jerusalem. Sources indicate that an earlier citadel, the Ptolemaic Baris, had also occupied a location overlooking the Temple's precincts. Although the exact location of the Baris is still debated, it is generally accepted to have stood north of the Temple Mount on the site later occupied by the Antonia Fortress. The Baris fell to Antiochus III at the turn of the 2nd century BCE and is absent from all accounts of the Maccabean Revolt. Despite the narratives which have the Acra constructed within a very short time-span, it was nevertheless formidable enough to weather long periods of siege. These factors, coupled with references in which the Baris was itself called an acra, have led some to suggest that the Baris and the Acra were in fact the same structure. Although both 1 Maccabees and Josephus seem to describe the Acra as a new construction, this may not have been the case. Antiquities of the Jews 12:253 may be translated to give the sense that the "impious or wicked" had "remained" rather than "dwelt" in the citadel, which could be taken to mean that the Acra had been standing before the revolt and that only the Macedonian garrison was new.Koen Decoster proposes that Josephus wrote of "a citadel in the lower part of the city" to an audience that would have been familiar with the Jerusalem of the 1st century CE—a city that did feature two citadels: the Antonia Fortress and the Herodian palace. As Josephus' Roman Jerusalem had already expanded to the higher western hill, "a citadel in the lower city" could have referred to anything located east of the Tyropoeon Valley, including the Antonia which stood north of the Temple and did indeed rise above and dominate it. In his view, this is the place Josephus must have had in mind when he wrote of the Acra.Opponents of a northern location counter that this site is not supported by the historical sources, and that this would place the Acra away from Jerusalem's population center. Unlike its predecessor and successor citadels, it was not meant as a defence against external threat, but rather to oversee the inhabited Jewish parts of the city, a role incompatible with a proposed northern location.
