Galata Tower

The Galata Tower (Galata Kulesi in Turkish) — called Christea Turris (the Tower of Christ in Latin) by the Genoese — is a medieval stone tower in the Galata district of Constantinople, Turkey, just to the north of the Golden Horn. One of the city's most striking landmarks, it is a high, cone-capped cylinder that dominates the skyline and affords a panoramic vista of Old Constantinople and its environs.

History
The tower was built as Christea Turris in 1348 during an expansion of the Genoese colony in Constantinople. It was the apex of the fortifications surrounding the Genoese citadel of Galata. The nine-story tower is 69,90 meters tall, and was the city's tallest structure when it was built.
