Istanbul, largest city and principal seaport of Turkey. It was the capital of both the Byzantine Empire and the Ottoman Empire.
The old walled city of Istanbul stands on a triangular peninsula between Europe and Asia. Sometimes as a bridge, sometimes as a barrier, Istanbul for more than 2,500 years has stood between conflicting surges of religion, culture, and imperial power. For most of those years it was one of the most coveted cities in the world.
The old city contains about 9 square miles (23 square km), but the present municipal boundaries stretch a great deal beyond. The original peninsular city has seven hills, requisite for Constantine’s “New Rome.” Six are crests of a long ridge above the Golden Horn; the other is a solitary eminence in the southwest corner. Around their slopes are ranged many of the mosques and other historic landmarks that were collectively designated a UNESCO World Heritage site in 1985.

By long tradition, the waters washing the peninsula are called “the three seas”: they are the Golden Horn, the Bosporus, and the Sea of Marmara. The Golden Horn is a deep drowned valley about 4.5 miles (7 km) long. Early inhabitants saw it as being shaped like a deer horn, but modern Turks call it the Haliç (“Canal”). The Bosporus (İstanbul Boğazı) is the channel connecting the Black Sea (Karadeniz) to the Mediterranean (Akdeniz) by way of the Sea of Marmara (Marmara Denizi) and the straits of the Dardanelles. The narrow Golden Horn separates old Istanbul (Stamboul) to the south from the “new” city of Beyoğlu to the north; the broader Bosporus divides European Istanbul from the city’s districts on the Asian shore—Üsküdar (ancient Chrysopolis) and Kadıköy (ancient Chalcedon).
Like the forces of history, the forces of nature impinge upon Istanbul. The great rivers of Russia and middle Europe—the Danube, Don, Dnieper, and Dniester—make the Black Sea colder and less briny than the Mediterranean. The Black Sea waters thrust southward through the Bosporus, but beneath them the salty warm waters of the Mediterranean push northward as a powerful undercurrent running through the same channel.

The prevailing northeast wind, or poyraz, comes from the Black Sea, giving way at times during the winter to an icy blast from the Balkans known as the karayel, or “black veil,” capable of freezing the Golden Horn and even the Bosporus. The lodos, or southwest wind, can raise storms on the Sea of Marmara.
Fire, earthquake, riot, and invasion have ravaged Istanbul many times, more than 60 conflagrations and numerous earthquakes being important enough to have been recorded in history. The traces of these disasters, though, have been swept away in waves of intensive urban development: today wide roadways run through the historic quarters of the old city, and unpaved alleys overhung with old wooden houses coexist with modern high-rise buildings, office parks, and shopping malls.
Portions of the walls of Stamboul remain. The land walls, which isolate the peninsula from the mainland, were breached only once, by cannon of the Ottoman sultan Mehmed II (the Conqueror) in 1453, at the spot since called Cannon Gate (Top Kapısı). The walls are 4.5 miles (7 km) long and consist of a double line of ramparts—the inner built in 413, the outer in 447—protected by a moat. The higher inner wall is about 30 feet (9 metres) high and 16 feet (5 metres) thick and is studded with 60-foot (18-metre) towers about 180 feet (55 metres) apart. Of 92 turrets originally raised on the outer wall, 56 are still standing.
The sea walls were built in 439. Only short sections of their 30-foot- (9-metre-) high masonry still remain along the Golden Horn. Intact, these walls had 110 towers and 14 gates. The walls along the Sea of Marmara, which stretch about 5 miles (8 km) from Seraglio Point, curving around the bottom of the peninsula to join the land walls, had 188 towers; they were, however, only about 20 feet (6 metres) high, because the Marmara currents provided good protection against enemy landings. Most of these walls still stand.
Within the city walls are the seven hills, their summits flattened through the ages but their slopes still steep and toilsome. Geographers number them from the seaward tip of the peninsula, proceeding inland along the Golden Horn, the last hill standing alone where the land walls reach the Sea of Marmara.
The Galata and Atatürk bridges cross the Golden Horn to Beyoğlu. Each day before dawn their centre spans are swung open to allow passage to seagoing ships. The shores of the Horn, served by water buses, are a jumble of docks, warehouses, factories, and occasional historical ruins. Ferries to the Asian side of Istanbul leave from under the Galata Bridge. Istanbul has three of the world’s longest suspension bridges: Bosporus I (Boğazici) Bridge (completed in 1973), with a main span of 3,524 feet (1,074 metres); Bosporus II, the Fatih Sultan Mehmed Bridge (1988), 3,576 feet (1,090 metres); and Bosporus III, the Yavuz Sultan Selim Bridge (2016), 4,620 feet (1,408 metres). Two tunnels under the Bosporus, one for passenger rail and one for automobile traffic, were opened in 2013 and 2016 respectively.
Beyoğlu, considered to be “modern Istanbul,” remains, as it has been since the 10th century, the foreign quarter. Warfare and fires have left standing only a few structures that were built earlier than the 19th century. The approach from the Golden Horn is steep, and a funicular railway runs between the Galata waterfront and the Pera Plateau. On the heights are the big hotels and restaurants, the travel bureaus, theatres, the opera house, the consulates, and many Turkish government offices.
