Galata (in Greek was known as Galatás, Γαλατᾶς) was a neighbourhood opposite Constantinople (today's Istanbul, Turkey), located at the northern shore of the Golden Horn, the inlet which separates it from the historic peninsula of old Constantinople. The Golden Horn is crossed by several bridges, most notably the Galata Bridge. The medieval citadel of Galata was a colony of the Republic of Genoa between 1273 and 1453. The famous Galata Tower was built by the Genoese in 1348 at the northernmost and highest point of the citadel. At present, Galata is a quarter within the borough of Beyoğlu (Pera) in Istanbul, and is known as Karaköy.
There are several theories concerning the origin of the name Galata. The Greeks believe that the name comes either from Galatai (meaning "Gauls"), as the Celtic tribe of Gauls (Galatians) were thought to have camped here during the Hellenistic period before settling into Galatia in central Anatolia; or from galatas (meaning "milkman"), as the area was used by shepherds for grazing in the Early Medieval (Byzantine) period. Italians believe the name comes from calata meaning slope or descent, because Galata, which is a former Genoese colony, is located on a hill that descends to the Bosphorus.Galata has subsequently been re-adopted by the city of Genoa in the naming of its naval museum Galata Museo del Mare.
