The Galata Tower, officially the Galata Tower Museum, is an old Genoese tower in the Galata part of the Beyoğlu district of Istanbul, Turkey. Built as a watchtower at the highest point of the (lost) Walls of Galata, the tower is now an exhibition space and museum, and a symbol of Beyoğlu and Istanbul.

The Genoese colonies were a series of economic and trade posts in the Mediterranean and Black Seas. Some of them had been established directly under the patronage of the republican authorities to support the economy of the local merchants, while others originated as feudal possessions of Genoese nobles, or had been founded by powerful private institutions, such as the Bank of Saint George.
