Aelia Capitolina (/ /; Latin in full: COLONIA AELIA CAPITOLINA) was a Roman colony, built under the emperor Hadrian on the site of Jerusalem, which was in ruins since the siege of 70 AD, leading in part to the Bar Kokhba revolt of 132–136 AD. Aelia Capitolina remained the official name of Jerusalem  until 638 AD when the Arabs conquered the city and kept the first part of it as 'إلياء' (Iliyā').
Aelia came from Hadrian's nomen gentile, Aelius, while Capitolina meant that the new city was dedicated to Jupiter Capitolinus, to whom a temple was built on the site of the former Jewish temple, the Temple Mount. (The Latin name Aelia is the source of the much later Arabic term Iliyā' (إلياء), a 7th-century Islamic name for Jerusalem.)
Jerusalem, once heavily rebuilt by Herod, was still in ruins following the decisive siege of the First Jewish–Roman War in 70 AD. Josephus – a contemporary historian and apologist for Judaism who was born in Jerusalem and fought the Romans in that war – reports that "Jerusalem ... was so thoroughly razed to the ground by those that demolished it to its foundations, that nothing was left that could ever persuade visitors that it had once been a place of habitation."
When the Roman Emperor Hadrian vowed to rebuild Jerusalem from the wreckage in 130 AD, he considered reconstructing Jerusalem as a gift to the Jewish people. The Jews awaited with hope, but then after Hadrian visited Jerusalem, he was told that rebuilding the Second Temple would encourage sedition. He then decided to rebuild the city as a Roman colony which would be inhabited by his legionaries.[page needed] Hadrian's new plans included temples to the major regional deities, and certain Roman gods, in particular Jupiter Capitolinus.
The Jewish Bar Kokhba revolt, which took the Romans three years to suppress, enraged Hadrian, and he became determined to erase Judaism from the province. Circumcision was forbidden, Iudaea province was renamed Syria Palaestina and Jews expelled from the city.
Indeed, following the Bar Kokhba revolt, Emperor Hadrian combined Iudaea Province with neighboring provinces under the new name of Syria Palaestina, dispensing with the name of Judea. The city was renamed "Aelia Capitolina", and rebuilt it in the style of a typical Roman town. Jews were prohibited from entering the city on pain of death, except for one day each year, during the holiday of Tisha B'Av. Taken together, these measures (which also affected Jewish Christians) essentially "secularized" the city. The ban was maintained until the 7th century, though Christians would soon be granted an exemption: during the 4th century, the Roman Emperor Constantine I ordered the construction of Christian holy sites in the city, including the Church of the Holy Sepulchre. Burial remains from the Byzantine period are exclusively Christian, suggesting that the population of Jerusalem in Byzantine times probably consisted only of Christians.
Till the time of Constantine, and for at least two centuries later, Aelia remained the official name and usual geographical designation ; was still longer continued in Christian writings; and even passed over into Arabic as "Iliyā" 
In the fifth century, the eastern continuation of the Roman Empire that was ruled from the recently renamed Constantinople, maintained control of the city. Within the span of a few decades, the city shifted from Byzantine to Persian rule, then back to Roman-Byzantine dominion. Following Sassanid Khosrau II's early seventh century push through Syria, his generals Shahrbaraz and Shahin attacked Jerusalem (Persian: Dej Houdkh) aided by the Jews of Palaestina Prima, who had risen up against the Byzantines.
In the Siege of Jerusalem of 614 AD, after 21 days of relentless siege warfare, Jerusalem was captured. Byzantine chronicles relate that the Sassanids and Jews slaughtered tens of thousands of Christians in the city, many at the Mamilla Pool, and destroyed their monuments and churches, including the Church of the Holy Sepulchre. The conquered city would remain in Sassanid hands for some fifteen years until the Byzantine Emperor Heraclius reconquered it in 629.
Byzantine Jerusalem was conquered by the Arab armies of Umar ibn al-Khattab in 638 AD. Among Muslims of Islam's earliest era it was referred to as Madinat bayt al-Maqdis ("City of the Temple") which was restricted to the Temple Mount. The rest of the city was called "Iliya", reflecting the Roman name given the city following the destruction of 70 CE: Aelia Capitolina".
According to Eusebius, the Jerusalem church was scattered twice, in 70 and 135, with the difference that from 70-130 the bishops of Jerusalem have evidently Jewish names, whereas after 135 the bishops of Aelia Capitolina appear to be Greeks. Eusebius' evidence for continuation of a church at Aelia Capitolina is confirmed by the Bordeaux Pilgrim.
Plan of the city
The city was without walls, protected by a light garrison of the Tenth Legion, during the Late Roman Period. The detachment at Jerusalem, which apparently encamped all over the city’s western hill, was responsible for preventing Jews from returning to the city. Roman enforcement of this prohibition continued through the 4th century.
The urban plan of Aelia Capitolina was that of a typical Roman town wherein main thoroughfares crisscrossed the urban grid lengthwise and widthwise. The urban grid was based on the usual central north-south road (cardo) and central east-west route (decumanus). However, as the main cardo ran up the western hill, and the Temple Mount blocked the eastward route of the main decumanus, a second pair of main roads was added; the secondary cardo ran down the Tyropoeon Valley, and the secondary decumanus ran just to the north of the Temple Mount. The main Hadrianic cardo terminated not far beyond its junction with the decumanus, where it reached the Roman garrison's encampment, but in the Byzantine era it was extended over the former camp to reach the southern walls of the city.
The two cardines converged near the Damascus Gate, and a semicircular piazza covered the remaining space; in the piazza a columnar monument was constructed, hence the Arabic name for the gate - Bab el-Amud (Gate of the Column). Tetrapylones were constructed at the other junctions between the main roads.
This street pattern has been preserved in the Old City of Jerusalem to the present. The original thoroughfare, flanked by rows of columns and shops, was about 73 feet (22 meters) wide, but buildings have extended onto the streets over the centuries, and the modern lanes replacing the ancient grid are now quite narrow. The substantial remains of the western cardo have now been exposed to view near the junction with Suq el-Bazaar, and remnants of one of the tetrapylones are preserved in the 19th century Franciscan chapel at the junction of the Via Dolorosa and Suq Khan ez-Zeit.
As was standard for new Roman cities, Hadrian placed the city's main Forum at the junction of the main cardo and decumanus, now the location for the (smaller) Muristan. Adjacent to the Forum, at the junction of the same cardo, and the other decumanus, Hadrian built a large temple to Venus, which later became the Church of the Holy Sepulchre; despite 11th century destruction, which resulted in the modern Church having a much smaller footprint, several boundary walls of Hadrian's temple have been found among the archaeological remains beneath the Church. The Struthion Pool lay in the path of the northern decumanus, so Hadrian placed vaulting over it, added a large pavement on top, and turned it into a secondary Forum; the pavement can still be seen under the Convent of the Sisters of Zion.
