ANTONIA, a citadel of Jerusalem, the origin of which we have in Josephus: who says, that Hircanus, the first high-priest of that name, built Baris near the temple, a house with turrets, where he generally resided. Herod afterwards made it stronger, for the security and defence of the temple; and in honour of Mark Antony, who then commanded in the east, called it Antonia. It was very extensive, and could accommodate a Roman legion: from it there was a full view of the temple.
