ISTANBUL
Istanbul (Turkish: İstanbul) is Turkey’s most populous city as well as its cultural and financial hub. Located on both sides of the Bosphorus, the narrow strait between the Black Sea and the Marmara Sea, Istanbul bridges Asia and Europe both physically and culturally

Expanding the ancient Greek colony of Byzantium by the order of the Roman Emperor Constantine the Great, the imperial city of Constantinople was for nearly a thousand years the last remaining outpost of the Roman (later termed Eastern Roman or Byzantine) Empire. It was finally conquered by the Ottoman Sultan Mehmed II on 29 May 1453, an event sometimes used to mark the end of the Middle Ages. It was the nerve centre for military campaigns that were to enlarge the Ottoman Empire dramatically.
By the mid 1500s, Istanbul, with a population of almost half a million, was a major cultural, political, and commercial centre. Ottoman rule continued until it was defeated in WWI and Istanbul was occupied by the allies. When the Republic of Turkey was born in 1923 after the War of Independence, Kemal Atatürk moved its capital to the city of Ankara.
However, Istanbul has continued to expand dramatically; today its population is approximately 14 million and increases at an estimated 400,000 immigrants per year. Industry has expanded even as tourism has grown.
With its long history at the center of empires, Istanbul offers a wealth of historic and religious places to take in.
The bulk of these ancient monuments, dating back to Roman, Byzantine, and Ottoman periods, including the Hagia Sophia, Topkapı Palace, Sultanahmet Mosque (Blue Mosque), and Basilica Cistern are located around Sultanahmet Square.
blue mosque

The mosque is popularly known as the Blue Mosque for the blue tiles adorning the walls of its interior.It was built from 1609 to 1616, during the rule of Ahmed I. Its Külliye contains a tomb of the founder, a madrasah and a hospice. The Sultan Ahmed Mosque is still popularly used as a mosque.
The Sultan Ahmed Mosque has one main dome, six minarets, and eight secondary domes. The design is the culmination of two centuries of Ottoman mosque development. It incorporates some Byzantine Christian elements of the neighboring Hagia Sophia with traditional Islamic architecture and is considered to be the last great mosque of the classical period
Hagia Sophia
Hagia Sophia (from the Greek: Ἁγία Σοφία, “Holy Wisdom”; Latin: Sancta Sophia or Sancta Sapientia; Turkish: Ayasofya) is a former Greek Orthodox patriarchal basilica (church), later an imperial mosque, and now a museum in Istanbul

From the date of its construction in 537 until 1453, it served as an Eastern Orthodox cathedral and seat of the Patriarchate of Constantinople, except between 1204 and 1261, when it was converted to a Roman Catholic cathedral under the Latin Empire. The building was a mosque from 29 May 1453 until 1931. It was then secularized and opened as a museum on 1 February 1935
Basilica Cistern
The Basilica Cistern (Turkish: Yerebatan Sarayı – “Sunken Palace”, or Yerebatan Sarnıcı – “Sunken Cistern”), is the largest of several hundred ancient cisterns that lie beneath the city of Istanbul. The cistern, located 500 feet (150 m) southwest of the Hagia Sophia on the historical peninsula of Sarayburnu, was built in the 6th century during the reign of Byzantine Emperor Justinian I
Located in the northwest corner of the cistern, the bases of two columns reuse blocks carved with the visage of Medusa. The origin of the two heads is unknown, though it is thought that the heads were brought to the cistern after being removed from a building of the late Roman period. There is no written evidence that suggests they were used as column pedestals previously. Tradition has it that the blocks are oriented sideways and inverted in order to negate the power of the Gorgons’ gaze however it is widely thought that one was placed sideways only to be the proper size to support the column. The upside down Medusa was placed that way specifically because she would be the same height right side up.
topkapi palace
Topkapi is the largest and oldest palace in the world to survive to our day. In 1924 it was turned into a museum at Atatiirk’s request. Situated on the acropolis, the site of the first settlement in Istanbul, it commands an impressive view of the Golden Horn, the Bosphorus and the Sea of Marmara. The palace is a complex surrounded by 5 km of walls and occupies an area of 700,000 sq. m at the tip of the historical peninsula.

Following the conquest of the city in 1453, the young Sultan Mehmet moved the capital of the empire to Istanbul, His first palace was located in the middle of the town. The second palace, which he built in the 1470’s, was initially called the New Palace, but in recent times it came to be known as the Topkapi Palace.
Topkapı is a classical example of Turkish palace architecture. It consists of tree- shaded courtyards, each serving a different purpose and opening onto one another with monumental gates. The courtyards are surrounded by functional buildings. From the time of its construction, the palace developed constantly with alterations and additions made by each sultan.
When the sultans moved to the ostentatious Dolmabahçe Palace in 1853, Topkapı lost its importance as the official royal residence and was left to deteriorate. It finally regained its former unpretentious beauty after fifty years of continuous restoration in the Republican era. Most of the objects exhibited in the palace today are unique masterpieces
As well as a royal residence, the palace was a setting for state occasions and royal entertainments. It is now a major tourist attraction and contains important holy relics of the Muslim world, including Muhammed’s cloak and sword
The Topkapı Palace is among the monuments contained within the “Historic Areas of Istanbul”, which became a UNESCO World Heritage Site in 1985
The different tiles, woodwork and architectural styles displayed in Topkapı Palace reflects the development of Turkish art and the harmonious existence of differing styles over the centuries
Some other attractions are dispersed throughout the city

CAPPADOCIA
Cappadocia (Turkish: Kapadokya) is an area in Central Anatolia in Turkey best known for its unique moon-like landscape, underground cities, cave churches and houses carved in the rocks.
The Cappadocian Region located in the center of the Anatolian Region of Turkey, with its valley, canyon, hills and unusual rock formation created as a result of the eroding rains and winds of thousands of years of the level, lava-covered plain located between the volcanic mountains Erciyes, Melendiz and Hasan as well as its troglodyte dwellings carved out of the rock and cities dug out into underground, presents an otherworldly appearance
The eruptions of these mountains which were active volcanoes in geological times lasted until 2 million years ago. A soft tuff layer was formed, 150 m in thickness, by the issuing lavas in the valley surrounded by mountains. The rivers, flood water running down the hillsides of valleys and strong winds eroded the geological formations consisting of tuff on the plateau formed with tuff layers, thus creating bizarre shapes called fairy Chimneys. These take on the names of mushroom shaped, pinnacled, capped and conic shaped formations.
The prehistoric settlements of the area are Koskhoyuk (Kosk Mound) in Nigde, Aksaray Asikli Mound, Nevsehir Civelek cave and, in the southeast, Kultepe, Kanis and Alisar in the environs of Kayseri.

This area with unusual topographic characteristics was regarded as sacred and called, in the Scythian/Khatti language, as Khepatukha, meaning “the country of the people of the chief god Hepat”, although there are more poetic claims on the origin of the region’s name, such as the Old Persian Katpatuka, which allegedly means “the land of beautiful horses”.
The tablets called Cappadocian Tablets and the Hittite works of art in Alisar are of the important remains dating from 2000s B.C. After 1200s B.C., the Tabal principality, of the Khatti Branches of Scythians, became strong and founded the Kingdom of Tabal. Following the Late Hittite and Persian aras, the Cappadocian Kingdom was established in 332 B.C.
During the Roman era the area served as a shelter for the early escaping Christians. There are also several underground cities used by early Christians as hideouts in Cappadocia.
