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-shaped, sheltered harbor that in the course of history has protected Greek, Roman, Byzantine, Ottoman and other maritime trade ships for thousands of years.

Ottoman architecture is an architectural style or tradition that developed under the Ottoman Empire over a long period, undergoing some significant changes during its history. It first emerged in northwestern Anatolia in the late 13th century and developed from earlier Seljuk Turkish architecture, with influences from Byzantine and Iranian architecture along with other architectural traditions in the Middle East. Early Ottoman architecture experimented with multiple building types over the course of the 13th to 15th centuries, progressively evolving into the classical Ottoman style of the 16th and 17th centuries. This style was a mixture of native Turkish tradition and influences from the Hagia Sophia, resulting in monumental mosque buildings focused around a high central dome with a varying number of semi-domes. The most important architect of the classical period is Mimar Sinan, whose major works include the Şehzade Mosque, Süleymaniye Mosque, and Selimiye Mosque. The second half of the 16th century also saw the apogee of certain decorative arts, most notably in the use of Iznik tiles.
Istanbul, formerly known as Constantinople, is the largest city in Turkey, serving as the country's economic, cultural and historic hub. The city straddles the Bosporus Strait, lying in both Europe and Asia, and has a population of over 15 million residents, comprising 19% of the population of Turkey. Istanbul is the most populous European city and the world's 15th-largest city.
Neolithic artifacts, uncovered by archeologists at the beginning of the 21st century, indicate that Istanbul's historic peninsula was settled as far back as the 6th millennium BCE. That early settlement, important in the spread of the Neolithic Revolution from the Near East to Europe, lasted for almost a millennium before being inundated by rising water levels. The first human settlement on the Asian side, the Fikirtepe mound, is from the Copper Age period, with artifacts dating from 5500 to 3500 BCE. In the European side, near the point of the peninsula (Sarayburnu) there was a settlement during the early 1st millennium BCE. Modern authors have linked it to the possible Thracian toponym Lygos, mentioned by Pliny the Elder as an earlier name for the site of Byzantium.
Karaköy, the modern name for the old Galata, is a commercial quarter in the Beyoğlu district of Istanbul, Turkey, located at the northern part of the Golden Horn mouth on the European side of Bosphorus.
Istanbul is known as the City on the Seven Hills. The city has inherited this denomination from Byzantine Constantinople which – consciously following the model of Rome – was built on seven hills too.
The architecture of Istanbul describes a large mixture of structures which reflect the many influences that have made an indelible mark in all districts of the city. The ancient part of the city is still partially surrounded by the Walls of Constantinople, erected in the 5th century by Emperor Theodosius II to protect the city from invasion. The architecture inside the city proper contains buildings and structures which came from Byzantine, Genoese, Ottoman, and modern Turkish sources. The city has many architecturally significant entities. Throughout its long history, Istanbul has acquired a reputation for being a cultural and ethnic melting pot. As a result, there are many historical mosques, churches, synagogues, palaces, castles and towers to visit in the city.
