Caeasarea is a reminder of Herod the Great’s determination to leave his mark on the world (building an entire artificial harbor to supplant Jaffa’s rocky natural one).
More importantly, it’s a reminder of the Apostle Paul’s determination to follow Jesus, wherever. This is where the Roman governors (including Pontius Pilate) had their palace, where Paul gave his defense, and where he was imprisoned for several years before being shipped off to Rome.
It’s also a really good place to simply bask in blue.
