Capo d'Istria, a fortified port situated on a small island in the government of Trieste and circle of Istria, Austria. The island is connected with the shore by a causeway half a mile in length, and possesses good accommodation for vessels, but little or no trade except in fish, wine, and oil. It is identified with the classical AEgida, and was afterwards named Justinopolis. For some time it was a free commonwealth, and then was conquered successively by the Venetians and Genoese, passing to Austria in 1797.
