First established as Byzantion in antiquity, the city rose to global prominence when Emperor Constantine declared it the imperial capital in 330 AD. After the Ottoman conquest in 1453, Istanbul entered a new chapter as Konstantiniyye, becoming a political, commercial, and cultural center of immense importance for centuries.

How Constantinople Becomes Istanbul?

Istanbul, formerly known as Constantinople, is a city that has attracted the attention of the world since ancient Byzantium. It is currently Turkey's largest city and the biggest city in the country. In the past, the Byzantine Empire was the capital of the Ottoman Empire. The secure walled old city of Istanbul stands on a peninsula between Asia and Europe. For more than 2,500 years, Istanbul has stood between conflicting waves of religion, culture, and imperial power, sometimes as a bridge, sometimes as a barrier. It has been one of the coveted cities of the world for centuries. The name Byzantium may have come from Byzant, the leader of the Greeks from the city of Megara, who, according to legend, conquered the peninsula from the idyllic Thracian tribes. In AD 196, the Roman emperor Septimius Severus, who razed the city for opposing him in a civil war, rebuilt the city, naming it Augusta Antonina in honor of her son. When the Great Constantine convert the city to his capital in 330 AD, he named it the New Rome. At the end of the 1st millennium BC, Greek speakers reportedly referred to trips there as "eis ten polin", "to the city" rather than "Constantinople". In the 13th century, a Greek idiom became the name of the city, which is still used today in its changed form: Istinpolin. This name became Istanbul after undergoing a series of changes over the centuries. The city continued to bear the millennial name until Turkey, officially changed the name of Constantinople to Istanbul in 1930.

Ottoman Architecture: Fatih Mosque

18th century and later mosques show the influence of importing European architects and masters who produced Baroque Islamic architecture (such as the Fatih Mosque, which was rebuilt between 1767 and 1771) and even Neoclassical styles, as did the 1853 Dolmabahçe Mosque. Large mosques were generally built in the form of a kulliye (complex). Among them, Qur'an schools (madrasahs), baths, boarding houses and cafeterias, tombs for the king, and distinguished people.

There are more than 400 fountains in Istanbul. Some simply flow from wall niches, but others are pavilions erected as public benefactors. The most magnificent of these was Sultan III's throne behind the apse of Hagia Sophia in 1728. It was built by Ahmed III. Ahmed fountain. It is square in shape with marble walls and bronze grilles, a mixture of Turkish and Western Rococo styles.

City Walls of Constantinople

Istanbul Old City (Sultanahmet-Fatih)

The old city (Sultanahmet)measures approximately 23 km2, but the current municipal boundaries extend far beyond. The original peninsula city had seven hills, necessary for Constantine's "New Rome". Six of them are the tops of a long ridge above the Golden Horn; the other is a lonely hill in the southwest corner. Around its slopes are many mosques and other historical landmarks that were collectively designated as UNESCO World Heritage sites in 1985

Sevenhill City Istanbul

The Golden Horn, the Bosphorus, and the Sea of Marmara are the effective coastal areas of Istanbul. The Golden Horn is a valley filled with water for about 7 km. Early inhabitants saw the area of the present Golden Horn as antlers (golden horn: golden horn), but foreigners call it the Golden Horn (“Gulf”). The Bosphorus is the channel connecting the Black Sea to the Mediterranean Sea via the Sea of Marmara and the Dardanelles. The Golden Horn separates the old Istanbul (Fatih) in the south from the city of Beyoğlu in the north; The widerBosphorusseparates European Istanbul from the city's Asian side districts, Üsküdar (ancient Chrysopolis) and Kadıkoy (ancient Chalcedony). Pouring into one of the world's most important passages, the Black Sea waters flow south through the Bosphorus, but beneath them, the salty warm waters of the Mediterranean are pushed northward as a strong undercurrent passing through the same channel.

How is Settlement Type in Istanbul

Fire, earthquake, rebellion, and occupation had ravaged Istanbul many times, with more than 60 fires and countless earthquakes that were significant enough to go down in history. Still, these disasters did not wash away this city: today wide roads run through the historic quarters of the old city, and unpaved streets lined with old wooden houses coexist with modern high-rises, office parks. There are hundreds of shopping centers in the old city, albeit small, in Istanbul.

Some of the city walls of Istanbul remain. The land walls separating the peninsula from the mainland, the traces of the Ottoman Sultan 2. Mehmed in 1453, at the point called Topkapı at this time, is remembered. The city walls surrounding Istanbul are 7 km long and the inner part was protected by ditches at the time of its construction, it consists of double rows of walls built in 413 and the outer part built-in 447. The higher inner wall is about .9 meters high and 5 meters thick and is adorned with 18-meter towers about 55 meters apart. Although the outer walls of the walls are made of 92 towers, only 56 are still standing. The sea walls were built in 439. Only short sections of the walls remain along the Golden Horn. The strong Golden Horn walls had 110 towers and 14 gates. The ramparts, which stretched for about 8 km from Sarayburnu and along the Marmara Sea, curved at the bottom of the peninsula to join the land walls, had 188 towers; however, the walls were only 6 meters high, as the Marmara currents provide good protection against enemy attacks. Most of the city walls are still standing.

The Most Important Ottoman Monuments in Istanbul

Like the Greeks, Romans, and Byzantines who settled in this majestic city before the Ottomans, the new rulers loved the city and spent most of their treasures and energies beautifying the city. When the Turks conquered Constantinople, they changed the character of the city by covering the ridges of seven hills with domes and minarets. Starting from 1300 on the Anatolian side and continuing its existence until 1922, the Ottoman dynasty continued to build new important structures almost until the end of its generation. Its most imposing mosques were built from the mid-15th century to the mid-16th century and are named after Mimar Sinan, the greatest of the architects. These Atik Sinan, Sinan from Balikesir, and Architect Sinan. Although the building was deeply influenced by the Persian traditions of the Seljuk Turks, the style was blended with the dominant Hellenic and Byzantine traditions of the city. Architect Sinan's masterpiece and burial place is the Süleymaniye Mosque (1550–57), inspired by, but not copied from, Hagia Sophia. It is ranked as one of the largest buildings in the world. Probably the most popular of all mosques in Istanbul is the Blue Mosque, the mosque of Sultan Ahmed I (1603-1617 Ottoman sultan), with six instead of the traditional four

Almost nothing remains of Byzantium, which was chosen by I.Constantine known as the founder of the Eastern Roman Empire, as the new location of New Rome, and the powerful city he built there. Constantine's column, the burnt column (Çemberlitaş), connected by metal braces, still stands next to the Nuruosmaniye mosque complex, but there is no evidence that any structure in the city dates to his period. Constantine completed the Hippodrome begun by Septimius Severus but was expanded and rebuilt by his successors until the 5th century. Only its curved end remains with three columns along the central Spina: an Obelisk removed from Egypt by the Roman emperor I. Theodosius, the serpentine column's serpent heads discarded after the Battle of Plataea, in which the Greeks defeated the Persians in 479 BC.

Basilica Cistern

The aqueduct, which was built by Emperor Valens in 366 in order to protect the water flowing from Belgrad forests to Istanbul through aqueducts, and to reduce the water needs of the city in summer months, was built in limestone as two floors. Some of the huge open water cisterns of the Byzantine period now serve the gardens. Among the more than 80 closed cisterns that have survived to the present day, one of the most beautiful and mysterious structures of Istanbul is the Basilica Cistern or the Basilica Cistern, also known as the Basilica Cistern in Turkish.

Best Ottoman Palaces To Visit-Topkapi Place

Galata Tower

To the north, towards the Golden Horn and covering the entire end of the promontory, is the Imperial Palace (Topkapi Palace), surrounded by walls. It was started to be used by Fatih Sultan Mehmed in 1462 and the administration of the Ottoman Empire was provided from here for 500 years. Foreign ambassadors were hosted in this palace and Bab-ı Hümayun, which was mistranslated as “The Porte” by the Westerners, was accepted from the Imperial Gate. Topkapi Palace consists of single-story rubble structures gathered around three courtyards. The most important structures are the Tiled Kiosk, built-in 1472; Supply Room; Hırka-i Şerif, where the remains of prophet Muhammad are found; and the Baghdad Pavilion, built to commemorate the capture of Baghdad in 1638. Topkapi Palace, as well as the living space, was also responsible for the protection of the treasury; It has important collections of manuscripts, china, armor, textiles, and jewelry. After the Old Palace was abandoned, the sultans had palaces built for themselves in the Beylerbeyi Palace (1865), the flamboyant Dolmabahçe Palace (1853), the Çırağan Palace (1874), and along the Bosphorus. From 1876 to 1909, the Ottoman Sultan The residence of II. Abdülhamid was Yıldız Palace

Galata Tower

The Galata region is a residential area for foreign traders (Genoese) who enjoy overseas privileges outside the city walls. After the Ottomans conquered the city in 1453, all foreigners who were not citizens of the empire were restricted to stay in this area. Today, around Istiklal Street, there are buildings of various nationalities, including schools, churches, and hospitals. Eventually, the Galata area became a very crowded place, so the buildings were moved up the hillside (up from Kabataş, Karaköy, Kasımpaşa). The most important settlement lived in the Pera region. Foreigners who wanted to visit the Topkapi Palace, where the Ottoman Empire had been ruled for centuries, could only do so in the company of one of the sultan's janissaries (elite soldiers).

Hagia Sophia

The biggest legacy from the capital of the destroyed empire is 25 Byzantine churches. Many of these are still used (as churches or mosques). The highest of the Orthodox churches is Hagia Sophia, which is considered one of the most magnificent indoor places of worship in the world and means Divine Wisdom. Contemporary and neighbor St. Irene was dedicated to "Divine Peace". Many art historians consider the dome of Hagia Sophia (132 meters in diameter) the most beautiful in the world. The St. Irene church was built by Constantine in 325 on the foundations of a pagan temple. It was enlarged by Konstans and after the fire in 415 II. It was rebuilt by Theodosius. The church was burned again in the Nika Revolt of 532 and was rebuilt by Justinian. The dome was destroyed in the earthquake in 559, then it was rebuilt on a small scale and strengthened from the outside. It was restored in the middle of the 14th century. In 1453, it was converted into a mosque with a minaret and a large chandelier was added to it and was turned into a museum in 1935. The church, which served as a museum for 86 years, was used as a mosque again on July 24, 2020, with the name of Hagia Sophia-i Kebir Cami-i Şerifi.

The Church of Saints Sergius and Bacchus was erected by Justinian between 527 and 536 as a thanksgiving gift. The emperor Anastasius I appeared to mediate for Justinian, who was allegedly sentenced to death for conspiracy, two saintly soldiers. The church was built as a domed octagon within a rectangle, with a Byzantine interior with columns and galleries. Today, it is open to worship as the (little) Kucuk Hagia Sophia Mosque.
