Herod the Great (reigned in Judea 37 to 4 BC) built Caesarea from 29 to 22 BC and dedicated this lavish city to Augustus Caesar. The only written evidence (outside the Gospels) that Pontius Pilate existed was discovered in Caesarea.
The city lost importance after 614 AD until the port was restored during the Crusades. The Mamelukes destroyed the city in the late 13th century.
