Galata originates from "Galat," a word used by the Byzantines to indicate the Goths, or from "Galatini" meaning "milk." Besides the names Beyoglu and Pera, this area is also known as Galata. The reason behind this is that the slightly sloped section stretching from Tunel to the shores of Halic is called Galata due to the Galata Tower. During the reign of Byzantines, Genoese conquered the region, which stood at opposite shores of old Istanbul, and they decided to build a tower.
Their aim was to surround the region with walls and they wanted to build a watchtower in the middle of the wall for defense purposes. At the time, they named the Tower "Jesus Tower." The tower originally had a spire and a large cross on its top.
