Istanbul is a bridge between Europe and Asia, the Black Sea and the Mediterranean, a position that endows it with one of the most unique and beautiful settings in the world. For, between the hills on the European and Asiatic shores flows the Bosphorus, the brightest gem in the diadem of nature.

"This beautiful strait, sometimes spelled Bosporus and sometimes Bosphorus, was so called from the earliest ages by the ancients; from the mythology of 10, the mistress of Jupiter, having passed over it in the shape of a cow. It resembles the Dardanelles, in length, breadth and current, and like it, is a narrow separation which divides Europe from Asia; but it has many features familiar to itself. Instead of being a solitary stream running between deserted shores, it is a body of water full of life and animation, winding its way through banks covered with palaces and villages, shaded with magnificent forest trees, presenting to the eye, at every mile, a new scene of crowded existence."

The Bosphorus has an inlet, a natural harbor which is an arm of the Sea of Marmara, called the Golden Horn. It is a deeply drowned valley about 7 km long. Two streams, Ali Bey and Kagithane flow into the Golden Horn which was so named as the early inhabitants saw it as shaped like the horns of a stag or water buffalo. Turks call it the Halic, i.e. the Gulf.

The Bosphorus itself has two pleasant rivulets on its Asiatic shore, called Göksu and Kucuksu which empty themselves into the Bosphorus between the villages of Anadoluhisari and Kandilli.

The two streams flowing into the Golden Horn were named by foreigners as the Sweet Waters of Europe, while Göksu and Kucuksu were known as the Sweet Waters of Asia.

Golden Horn, Istanbul, Turkey

As the sun sets in Istanbul, its yellow light blazes on the waters of the Golden Horn, giving this freshwater estuary its romantic name…we think. (The name in English is a direct translation of the Byzantine name Chrysokeras.)

“Golden Horn” is its Western name. Its Turkish name, Haliç, (hah-LEECH, from Arabic) has nothing to do with gold or horns. Haliç, short for Haliç-i Dersaadet, means “The Bay of Istanbul.”
