The Galata Tower is a medieval Genoese tower in the Galata part of Istanbul, Turkey. Built as a watchtower at the highest point of the mostly demolished Walls of Galata, the tower is now an exhibition space and museum, and a symbol of Beyoğlu and Istanbul.
During the Byzantine period the Emperor Justinian had a tower erected in what was to become Galata. This tower was destroyed by the Crusaders during the Sack of Constantinople in 1204. In 1267 a Genoese colony was established in the Galata part of Constantinople. It was surrounded by walls and the Galata Tower was first built at their highest point in Romanesque style in 1348 during an expansion of the colony. At the time the Galata Tower was the tallest building in the city.
After the Ottoman conquest of Constantinople in 1453, the Genoese colony was abolished and most of the walls of the citadel were later pulled down in the 19th century, during the northward expansion of the city in the districts of Beyoğlu and Beşiktaş; though small parts of the Genoese walls in Galata have survived. The tower was allowed to survive and was turned into a prison. It was from its roof that, in 1638, Hezarfen Ahmed Çelebi supposedly strapped on wings and made the first intercontinental flight, landing in the Doğancılar Meydanı in Üsküdar on the Asian side of the city, a story of doubtful authenticity recounted by the Ottoman travel writer, Evliya Çelebi.
In 2020 the Tower was splendidly restored then reopened as a museum now open for the public and the many tourists visiting Istanbul. It is mainly popular for the 360-degree view of Istanbul visible from its observation deck.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
