Caesarea was built by Herod the Great along the Mediterranean coast as a monumental port city dedicated to Caesar Augustus. It played a key role in early Christianity, as the place where Paul was imprisoned before being sent to Rome. Excavated by several archaeological expeditions, the site features impressive Roman ruins, including a theater, hippodrome, and a luxurious palace. Today, visitors explore its archaeological wonders and enjoy views of the Mediterranean Sea from the ancient harbor.
