It is an important site for Christians for a number of reasons. First, the so called Pilate Stone which actually identifies Pontius Pilate as the governor or prefect of the land of Judea was found here. Secondly, the first convert among the Gentiles, Cornelious, was baptized here. Third, Paul was held prisoner here for 2 years and Philip the Apostle lived here.
The amphitheater could seat 4000 spectators.
The once fantastic Roman harbor has all but fallen into the sea.
