Construction of churches in Palestine: Constantine and his mother Helena order churches to be built in the most important Christian sites: Bethlehem, Jerusalem, Mount of Olives (inaugurated in 326), and Allon–Moreh near Hebron.

 330 CE:  CONSTANTINOPLE

Refounding of Constantinople on the site of an already existing city, Byzantium, settled in the early days of the Greek colonial expansion around 671–662 BCE. The new walled capital of the Roman Empire is built–up by Constantine I and named after him.

Constantinople is astride the Bosporus and the Marmara Sea. The western side of Constantinople (the walled part) on the Bosporus is Europe, and the eastern side, Asia. The city is astride the route from the Black Sea to the Mediterranean. The sequential sea route north to south is: Black Sea > Bosporus Strait > Sea of Marmara > Dardanelles Strait > Aegean Sea in the Mediterranean.

Constantinople was renamed “Istanbul” in 1930 by Ataturk.

335 CE:  PALESTINE HAPPENINGS

Inauguration of the basilica of the Holy Sepulchre in Jerusalem on the site identified by Christian tradition as Jesus’ burial place; the probable renewal of the interdict on Jews to reside in Jerusalem which has been in force since Hadrian’s days; about the same time, an attempt was made by a converted Jew known as Joseph the Apostate to build churches in the Galilee; his failure demonstrates that the Galilee is still a predominantly Jewish region where, unlike Judea and the center of Palestine, Christianity has not yet taken root.
