Bosphorus (left), the entrance of the Golden Horn (center and right), and the
Sea of Marmara (distance) with the
Princes' Islands on the horizon Archaeological records show a significant urban presence on and around the Golden Horn dating back to at least the 7th century BC, with smaller settlements going as far back as 6700 BC as confirmed by recent discoveries of ancient ports, storage facilities, and fleets of trade ships unearthed during construction work for the
Yenikapı subway station and the
Marmaray tunnel project. Indeed, the deep natural harbor provided by the Golden Horn has always been a major economic attraction and strategic military advantage for inhabitants of the area. Emperor
Constantine I established
Nova Roma (later
Constantinople) on top of the existing city of
Byzantium to capitalize on the same benefits, as did the founders of the previous settlement and its modern successor,
Istanbul. The
Eastern Roman Empire had its naval headquarters there, and walls were built along the shoreline to protect the city of
Constantinople from naval attacks.
The Great Chain of the Golden Horn . At the entrance to the Horn on the northern side, a
large chain was pulled across from
Constantinople to the
old Tower of Galata to prevent unwanted ships from entering. Known among the Byzantines as the
Megàlos Pyrgos (meaning "Great Tower" in
Greek), this tower was largely destroyed by the Latin Crusaders during the
Fourth Crusade in 1204. In 1348, the
Genoese built a new tower nearby which they called
Christea Turris (Tower of Christ), now called
Galata Tower. There were three notable times when the chain across the Horn was either broken or circumvented. In the 10th century the
Kievan Rus' dragged their longships out of the
Bosphorus, around
Galata, and relaunched them in the Horn; the Byzantines defeated them with
Greek fire. In 1204, during the
Fourth Crusade,
Venetian ships were able to break the chain with a
ram. In 1453,
Ottoman Sultan
Mehmed II, having failed in his attempt to break the chain with brute force, instead used the same tactic as the
Rus'; towing his ships across Galata over
greased logs and into the estuary. After the
Ottoman conquest of Constantinople in 1453,
Mehmed II resettled ethnic Greeks along the Horn in the
Phanar (today's Fener). Balat continued to be inhabited by Jews, as during the Byzantine age, though many Jews decided to leave following the takeover of the city. This area was repopulated when
Bayezid II invited the Jews who were
expelled from Spain to resettle in
Balat. In 1502,
Leonardo da Vinci produced a drawing of a single-span bridge over the Golden Horn as part of a civil engineering project for Sultan
Bayezid II. Leonardo's drawings and notes regarding this bridge are currently displayed at the
Museo della Scienza e della Tecnologia in
Milan,
Italy. While the original design was never executed, the vision of Leonardo's Golden Horn Bridge was resurrected in 2001, when a
small footbridge based on Leonardo's design was constructed near
Ås in
Norway by
Vebjørn Sand. During World War 1, the area
was bombed by the British forces in 1918. Until the 1980s, the Horn was polluted with industrial waste from the factories, warehouses, and shipyards along its shores. It has since been cleaned, and the local fish, wildlife, and flora have been largely restored. The clean-up happened in two main phases under Mayor
Bedrettin Dalan in the 1980s and under Mayor
Recep Tayyip Erdoğan in the 1990s. Nowadays, the Golden Horn is settled on both sides, and there are parks along each shore. The
Istanbul Chamber of Commerce is also located along the shore, as are several
Muslim,
Jewish and
Christian cemeteries. Other institutions along the Horn's banks include museums, congress and cultural halls, supporting facilities of the
Turkish Navy, and campuses of various universities. Today, the Horn's history and natural environment make it a popular tourist attraction in Istanbul, visited by 10 million international vacationers annually. == Tersane Istanbul ==
