A sea-port on the Mediterranean, about midway between Carmel and Joppa. The city was built by Herod the Great and named after Augustus his patron. It became the seat of the governors of Palestine, and the place where their army was quartered. Paul was sent there to protect him from the intrigues of the Jews at Jerusalem (Acts 23:23,33). He was imprisoned there for two years (Acts 25:1-13). It was there that Peter opened the door to the Gentiles in the case of Cornelius and his friends (Acts 10:1, 24). The harbor was massively built, with a breakwater and landing wharfs: now all is in desolation without an inhabitant: much of the materials from its ruins have been carried away for building purposes. Its modern name is Kaisarieh.
