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 as the
Christea Turris (Tower of Christ) in
Romanesque style in 1348 during an expansion of the colony. At the time the Galata Tower, at , 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. From 1717, the Ottomans used the tower to look out for fires (on the Old Istanbul side of the city the
Beyazıt Tower served the same function). In 1794, during the reign of Sultan
Selim III, the roof was reinforced in lead and wood, but the stairs were severely damaged by a fire. Another fire damaged the building in 1831, after which further restoration work took place. In 1875, the tower's conical roof was destroyed during a storm. It remained without this roof for the rest of the Ottoman period but, many years later, during restoration work between 1965 and 1967, the conical roof was reconstructed. In 2020, the Tower was restored then reopened as a museum now open for the public and tourists. In 2023, restoration work began on the conical roof, with a focus on extending the lifecycle of the copper finial it once had as well. Other structural reinforcements were achieved on reinforced concrete elements and around the masonry walls, enabling improvements to the building's earthquake resiliency. A 3-meter-high protection tunnel was built around the tower to ensure the safety of visitors and the surrounding area. Galata Tower reopened to the visiting public on May 25, 2024, with a new visitor policy that capped visitor entry at 100 per hour. The tower is mainly popular for the 360-degree view of Istanbul visible from its observation deck. ==Dimensions==
