ACRA, in Ancient Geography, one of the hills of Jerusalem, on which stood the lower town, which was the old Jerusalem; to which was afterwards added Zion, or the City of David. It was probably called Acra, from the fortress which Antiochus built there in order to annoy the temple, and which Simon Maccabeus took and razed to the ground.

Acra Japygia, in Ancient Geography, called Salentia by Ptolemy; now Capo di Leuca: a promontory in the kingdom of Naples, the southernmost point of Otranto.
