Caesarea (), also Caesarea Maritima, Caesarea Palaestinae or Caesarea Stratonis, was an ancient and medieval port city on the coast of the eastern Mediterranean, and later a small fishing village. It was the capital of Roman Judaea, Syria Palaestina and Palaestina Prima, successively, for a period of 650 years and a major intellectual hub of the Mediterranean. Today, the site is part of the Caesarea National Park, on the western edge of the Sharon plain in Israel.

The site was first settled in the 4th century BCE as a Phoenician colony and trading village known as Straton's Tower after the ruler of Sidon. It was enlarged in the 1st century BCE under Hasmonean rule, becoming a Jewish village; and in 63 BCE, when the Roman Republic annexed the region, it was declared an autonomous city. It was then significantly enlarged in the Roman period by the Judaean client King Herod the Great, who established a harbour and dedicated the town and its port to Caesar Augustus as Caesarea.

During the early Roman period, Caesarea became the seat of the Roman procurators in the region."Founded in the years 22-10 or 9 B.C. by Herod the Great, close to the ruins of a small Phoenician naval station named Strato's Tower (Stratonos Pyrgos, Turns Stratonis), which flourished during the 3d to 1st c. B.C. This small harbor was situated on the N part of the site. Herod dedicated the new town and its port (limen Sebastos) to Caesar Augustus. During the Early Roman period, Caesarea was the seat of the Roman procurators of the province of Judea. Vespasian, proclaimed emperor at Caesarea, raised it to the rank of Colonia Prima Flavia Augusta, and later Alexander Severus raised it to the rank of Metropolis Provinciae Syriae Palestinae." A. Negev, "CAESAREA MARITIMA Palestine, Israel" in: Richard Stillwell et al. (eds.), The Princeton Encyclopedia of Classical Sites (1976).Isaac, B.H., The Near East Under Roman Rule: Selected Papers (Brill, 1997), p. 15 The city was populated throughout the 1st to 6th centuries CE and became an important early centre of Christianity during the Byzantine period. Its importance may have waned following the Muslim conquest of 640 when the city, then known in Arabic as Qisarya (), lost its status as provincial capital. After being re-fortified by Muslim rulers in the 11th century, it was conquered by the Crusaders, who strengthened and made it into an important port, which was finally slighted by the Mamluks in 1265.

Qisarya was a small fishing village in the early modern period. In February 1948, during the 1948 Palestine war and Nakba, some of its population fled following an attack on a bus by the Zionist militant group Lehi, and the remainder were expelled by the Palmach, who subsequently demolished its houses.: "As we have seen, Haganah policy until the end of March was non-expulsive. But there were one or two local, unauthorised initiatives... And there was one authorised expulsion. The inhabitants of Qisarya, south of Haifa, lived and cultivated Jewish (PICA) and Greek Orthodox church lands. One leading family evacuated the village on 10 January. Most of the population left – apparently for neighbouring Tantura – immediately after the 31 January LHI ambush of a bus that had just pulled out of Qisarya in which two Arabs died and eight were injured (one of the dead and several injured were from the village). The Haganah decided to occupy the site because the land was PICA-owned. But after moving in, the Haganah feared that the British might eject them. The commanders asked headquarters for permission to level the village. Yitzhak Rabin, the Palmah's head of operations, opposed the destruction – but he was overruled. On 19–20 February, the Palmah's Fourth Battalion demolished the houses. The 20-odd inhabitants who were found at the site were moved to safety and some of the troops looted the abandoned homes. A month later, the Arabs were still complaining to local Jewish mukhtars that their stolen money and valuables had not been returned. The Qisarya Arabs, according to Aharon Cohen, had 'done all in their power to keep the peace ... The villagers had supplied agricultural produce to Jewish Haifa and Hadera ... The attack was perceived in Qisarya – and not only there – as an attempt by the Jews to force them (the Arabs) living in the Jewish area, to leave ... The ruins of the ancient city beneath the depopulated village were excavated in the 1950s and 1960s for archaeological purposes.Raban and Holum, 1996, p. 54

Name Whilst the name Caesarea was frequently used alone for the subject of this article, various markers were used to differentiate the location from these other locations; these include "Palaestina" ("of Palestine"), "Maritima" ("by the sea"; Greek: Parálios), "Sebaste" and "Stratonis". "Palaestina" is the most common term used in ancient sources, but, since the creation of Israel in 1948, historians in the West have tended to use the term less frequently.

The Latin name Caesarea also referred to several other cities in the region, notably Caesarea near Mount Hermon and Caesarea the capital of Cappadocia.

History Straton's Tower Stratonos pyrgos (Straton's Tower) was founded in the 4th century BCE by Abdashtart I, or Straton I king of Sidon. It was first established as a Phoenician colony and trading village. In 90 BCE, Jewish ruler Alexander Jannaeus captured Straton's Tower as part of his policy of developing the shipbuilding industry and enlarging the Hasmonean kingdom. Straton's Tower remained a Jewish settlement for two more generations, until the area became dominated by the Romans in 63 BCE, when they declared it an autonomous city.

Herod the Great builds Caesarea

Caesarea was built in Roman Judea under the Jewish client King Herod the Great during 22-10/9 BCE near the ruins of the small naval station of Straton's Tower. The site, along with all of Judea, was awarded by Rome to Herod in 30 BCE."In the year 30 BCE the (Phoenician) village was awarded to Herod, who built a large port city at the site, and called it "Caesarea" in honor of his patron Octavian Augustus Caesar....The city transformed rapidly into a great commercial centre, and by the year 6 BCE became the headquarters of the Roman government in Palestine. Since Caesarea had no rivers or springs, drinking water for the prospering Roman and Byzantine city was brought via a unique high-level aqueduct, originating at the nearby Shuni springs, some 7.5 km northeast of Caesarea. [...] Caesarea served as a base for the Roman legions who quelled the Great Revolt that erupted in 66 BCE [sic], and it was here that their commanding general Vespasian was declared Caesar. After the destruction of Jerusalem, Caesarea became the most important city in the country: Pagans, Samaritans, Jews and Christians lived here in the third and fourth centuries CE.UNESCO tentative list:Caesarea The pagan city underwent vast changes under Herod, who renamed it Caesarea in honour of the Roman emperor, Caesar Augustus. Caesarea was known as the administrative, economic, and cultural capital of the Judean province from this time.

In 22 BCE, Herod began construction of a deep-sea harbour named Sebastos and built storerooms, markets, wide roads, baths, a temple to the goddess Roma and Emperor Augustus, and imposing public buildings.Crossan, 1999, p. 232 Herod built his palace on a promontory jutting out into the sea, with a decorative pool surrounded by stoas. Every five years, the city hosted major sports competitions, gladiator games, and theatrical productions in its theatre overlooking the Mediterranean Sea.

Sebastos harbor

Herod built the two jetties of the harbour between 22 and 15 BCE,Votruba, G., 2007, Imported building materials of Sebastos Harbour, Israel, International Journal of Nautical Archaeology 36: 325-335. and in 10/9 BCE he dedicated the city and harbour to Emperor Augustus (sebastos is Greek for augustus).Raban, A., 1992. Sebastos: the royal harbour at Caesarea Maritima - a short-lived giant, International Journal of Nautical Archaeology 21: 111-124. The pace of construction was impressive considering the project's size and complexity.Hohlfelder, R. 2007. "Constructing the Harbour of Caesarea Palaestina, Israel: New Evidence from ROMACONS Field Campaign of October 2005". International Journal of Nautical Archaeology 36:409-415. At its height, Sebastos was one of the most impressive harbours of its time. It had been constructed on a coast that had no natural harbours and served as an important commercial harbour in antiquity, rivaling Cleopatra's harbour at Alexandria. Josephus writes: "Although the location was generally unfavorable, [Herod] contended with the difficulties so well that the solidity of the construction could not be overcome by the sea, and its beauty seemed finished off without impediment."Holum, K. 1988. King Herod's Dream: Caesarea on the Sea. New York: Norton.

When it was built in the 1st century BCE, the harbour of Sebastos ranked as the largest artificial harbour built in the open sea, enclosing around 100,000 m2.George Menachery, 1987 in Kodungallur, City of St. Thomas, Azhikode, 1987, Chapter II note 19 quotes the National Geographic article: Robert L. Hohlfelder, "Caesarea Maritima, Herod the Great's City on the Sea". The National Geographic, 171/2, February 1987, pp. 260-79.2000 years ago, Caesarea Maritima welcomed ships to its harbour called Sebastos. Featuring innovative design and hydraulic concrete, this building feat set a standard for harbours to come. A monumental work, city and harbour were constructed on an unstable storm-battered shore, at a site lacking a protective cape or bay. The project challenged Rome's most skilled engineers. Hydraulic concrete blocks, some weighing anchored the north breakwater of the artificial harbour ... Caesarea Maritima, rival to Alexandria in the Eastern trade, a city worthy to be named for Herod's patron, Caesar Augustus, master of the Roman world, in view of its opulence and magnificence.Votruba, G. 2007. "Imported Building Materials of Sebastos Harbour, Israel." International Journal of Nautical Archaeology 36:325-335.

The breakwaters were made of lime and pozzolana, a type of volcanic ash, set into an underwater concrete. Herod imported over 24,000 m3 of pozzolana from the name-giving town of Puteoli, today Pozzuoli in Italy, to construct the two breakwaters: the southern one 500 meter, and the northern one 275 meter long.

A shipment of this size would have required at least 44 shiploads of 400 tons each. Herod also had 12,000 m3 of local kurkar stone quarried to make rubble and 12,000 m3 of slaked lime mixed with the pozzolana.

Architects had to devise a way to lay the wooden forms for the placement of concrete underwater. One technique was to drive stakes into the ground to make a box and then fill it with pozzolana concrete bit by bit. However, this method required many divers to hammer the planks to the stakes underwater and large quantities of pozzolana were necessary.

Another technique was a double planking method used in the northern breakwater. On land, carpenters would construct a box with beams and frames on the inside and a watertight, double-planked wall on the outside. This double wall was built with a gap between the inner and outer layer.Brandon, C., 1996, Cements, Concrete, and Settling Barges at Sebastos: Comparisons with Other Roman Harbor Examples and the Descriptions of Vitruvius, Caesarea Maritima: A Retrospective after Two Millennia, 25-40.

Although the box had no bottom, it was buoyant enough to float out to sea because of the watertight space between the inner and outer walls. Once it was floated into position, pozzolana was poured into the gap between the walls and the box would sink into place on the seafloor and be staked down in the corners. The flooded inside area was then filled by divers bit by bit with pozzolana-lime mortar and kurkar rubble until it rose above sea level.
