Palaestina Prima
During the Byzantine period, Caesarea became the capital of the new province of Palaestina Prima in 390. As the capital of the province, Caesarea was also the metropolitan see, with ecclesiastical jurisdiction over Jerusalem, when rebuilt after the destruction in the year 70. In 451, however, the Council of Chalcedon established Jerusalem as a patriarchate, with Caesarea as the first of its three subordinate metropolitan sees.
