Who Built Galata Tower & When? History Facts

5 min readLast updated: 2026-07-02

Galata Tower was built in 1348 by the Genoese — the merchant colonists of the Republic of Genoa — who named it Christea Turris, the "Tower of Christ." It was raised as the highest point of the fortification walls that ringed their colony of Galata, across the Golden Horn from Byzantine Constantinople. As of 2026 the tower is roughly 678 years old.

Galata Tower, built by the Genoese in 1348

When Was It Built?

The stone tower that stands today dates to 1348. This was the height of Genoese commercial power in the eastern Mediterranean, when Galata had grown into a prosperous, semi-autonomous trading city with its own walls, churches, warehouses, and harbour administration.

A wooden watchtower had existed on the same strategic hilltop in Byzantine times, centuries earlier, but it was a modest structure that was damaged and rebuilt many times. When people ask "what year was Galata Tower built," the widely accepted answer refers to the Genoese stone tower of 1348 — the building whose silhouette still dominates the skyline.

Who Built It?

The tower was built by the Genoese. After the Treaty of Nymphaeum, the Republic of Genoa was granted a trading colony on the northern shore of the Golden Horn, facing the Byzantine capital across the water. The colony administration financed the tower and Genoese military engineers supervised its construction using the limestone and rubble-core techniques typical of 14th-century military architecture.

It was not a standalone monument but the keystone of an entire defensive system — the highest point of the Genoese walls that enclosed the colony. For the fuller story of the colony and the empires that followed, see our history of Galata Tower.

Why Was It Built?

Galata Tower was built for defence, watch, and control of the approach. Three purposes stand out:

  • Observation — its commanding height let watchers monitor ship traffic entering the Golden Horn and see across to Constantinople.
  • Defence — as the apex of the fortification walls, it anchored the colony's protection against attack.
  • Domination — the tower announced Genoese wealth and power, standing taller than anything else in the city at the time.

Under the later Ottomans the tower found new uses. Most famously it became a fire-watch tower, where wardens scanned the wooden city for smoke and signalled the location of fires. It also served at various times as a lookout, a prison for prisoners of war, and a base for observation. The pointed conical roof is a later addition, and the tower was damaged and repaired several times across the centuries.

How Old Is It Today?

Counting from its 1348 construction, Galata Tower is roughly 678 years old in 2026. Few buildings in the world have stood so long while remaining in continuous use. Over those centuries it survived earthquakes and fires, changed rulers, and was restored repeatedly. Its most recent transformation came in 2020, when the Turkish Ministry of Culture and Tourism reopened it as a museum after a full restoration.

The Hezarfen Legend

No account of the tower's story is complete without its most famous legend. Around 1632, according to the Ottoman traveller Evliya Çelebi, Hezarfen Ahmet Çelebi fastened artificial wings and glided from the top of Galata Tower across the Bosphorus, landing on the Asian shore. Whether history or myth, the tale has bound the tower to the dream of human flight ever since. Read more in our guide to the legends of Galata Tower.
