Sarayburnu in the context of "Istanbul"

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.

There is evidence suggesting there were settlements around the region dating as far back as 6700 BC, and it is hard to define if there was any settlement on exact spot at city proper established, but earliest records about city proper begins around 660 BC when Greek settlers from the Attic town of Megara colonized the area and established Byzantium on the European side of the Bosphorus. It fell to the Roman Republic in 196 BC, and was known as Byzantium in Latin until 330, when the city, soon renamed as Constantinople, became the new capital of the Roman Empire. During the reign of Justinian I, the city rose to be the largest in the western world, with a population peaking at close to half a million people. Constantinople functioned as the capital of the Byzantine Empire, which effectively ended with the fall of Constantinople in 1453. Constantinople then became the capital of the Ottoman Turks.

The Historic Areas of Istanbul (Turkish: İstanbul'un Tarihî Alanları; Greek: Ιστορικές Περιοχές της Κωνσταντινούπολης, romanized: Historikés Periochés tīs Kōnstantinoúpolis; Ottoman Turkish: استانبولك تاریخي اﻻنلری) are a group of sites in the capital district of Fatih in the city of Istanbul, Turkey. These areas were added to the UNESCO World Heritage List in 1985.

It includes buildings and structures such as the Sarayburnu, the Topkapı Palace, the Hagia Sophia, the Sultan Ahmed Mosque, the Hagia Irene, Zeyrek Mosque, Süleymaniye Mosque, Little Hagia Sophia and the Walls of Constantinople.

The Golden Horn (Turkish: Altın Boynuz or Haliç) 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" (ancient Byzantium and Constantinople), 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.

Throughout its history, the Golden Horn has witnessed many tumultuous historical incidents, and has been depicted in numerous works of art.

Üsküdar (Turkish pronunciation: [ysˈcydaɾ]) is a municipality and district of Istanbul Province, Turkey. Its area is 35 km, and its population is 524,452 (2022). It is a large and densely populated district on the Anatolian (Asian) shore of the Bosphorus. It is bordered to the north by Beykoz, to the east by Ümraniye, to the southeast by Ataşehir and to the south by Kadıköy; with Karaköy, Kabataş, Beşiktaş, and the historic Sarayburnu quarter of Fatih facing it on the opposite shore to the west. Üsküdar has been a conservative cultural center of the Anatolian side of Istanbul since Ottoman times with its landmark as well as numerous tiny mosques and dergahs.

Previously known as Chrysopolis and Scutari, present-day Üsküdar is a major transport hub, with ferries to Eminönü, Karaköy, Kabataş, Beşiktaş and some of the Bosphorus suburbs. Üsküdar is a stop on the Marmaray rail service at the point where it starts its journey under the Bosphorus, re-emerging on the European side at Sirkeci. Via Marmaray, Üsküdar is linked to Gebze on the Asian side of the city and Halkali on the European side. Üsküdar is also a stop on the M5 Metro line to Çekmeköy. Buses run along the Bosphorus shore all the way up north to Anadolu Kavağı in Beykoz district. A bus service also operates to the summer town of Şile on the Black Sea.

The Maiden's Tower (Turkish: Kız Kulesi), also known as Leander's Tower (Tower of Leandros) since the Byzantine period, is a tower on a small islet at the southern entrance of the Bosphorus strait, 200 m (220 yd) from the coast of Üsküdar in Istanbul, Turkey.

The tower appeared on the reverse of the Turkish 10 lira banknote from 1966 to 1981.
