The Golden Horn is a major urban waterway and the primary inlet of the Bosphorus in Istanbul, Turkey. As a natural estuary that connects with the Bosphorus Strait at the point where the strait meets the Sea of Marmara, the waters of the Golden Horn help define the northern boundary of the peninsula constituting "Old Istanbul", the tip of which is the promontory of Sarayburnu, or Seraglio Point. This estuarial inlet geographically separates the historic center of Istanbul from the rest of the city, and forms a horn shape, sheltered harbor that in the course of history has protected Greek, Roman, Byzantine, Ottoman and other maritime trade ships for thousands of years.

The Bosporus or Bosphorus Strait is a natural strait and an internationally significant waterway located in Istanbul, Turkey. The Bosporus connects the Black Sea to the Sea of Marmara and forms one of the continental boundaries between Asia and Europe. It also divides Turkey by separating Anatolia from Thrace. It is the world's narrowest strait used for international navigation.

The body of water at the top is the Black Sea, the one at the bottom is the Marmara Sea, and the Bosporus is the winding waterway that connects the two. The western banks of the Bosporus constitute the geographic starting point of the European continent, while the banks to the east are the geographic beginnings of the continent of Asia. The city of
