A square fortress on the east side of Jerusalem, north of the temple area, with which it had a covered communication. There was a tower at each corner, and it was isolated by high walls and trenches. It was rebuilt by Herod the Great, and named after Mark Antony. Josephus often speaks of it. It was "the castle" from which soldiers came down to rescue Paul from the Jews in the temple; and from its stairs he addressed the multitude,
a fortress in Jerusalem, at the north-west corner of the temple area. It is called "the castle" (Ac 21:34,37). From the stairs of this castle Paul delivered his famous speech to the multitude in the area below (Ac 22:1-21). It was originally a place in which were kept the vestments of the high priest. Herod fortified it, and called it Antonia in honour of his friend Mark Antony. It was of great size, and commanded the temple. It was built on a plateau of rock, separated on the north from the hill Bezetha by a ditch about 30 feet deep and 165 feet wide.
A tower or fortress built by Herod the Great near the temple at Jerusalem in which he placed a guard to watch over the approaches to the sacred edifice. Josephus (Wars v. 5, 8) says it was situated "at the corner of two cloisters of the court of the temple; of that on the west, and that on the north; it was erected upon a rock fifty cubits in height and was on a great precipice." Where this precipice was is not known, for it is a much disputed question upon what part of the temple area the temple was built. There is a tower, now called Antonia, on the N.W. angle, and there are indications of a similar one having stood on the S.E. angle.
