Southeastern Turkey

Diyarbakır (also known as Diyarbekir) is the largest city in the Eastern Anatolia region. Diyarbakır, with its mighty black basalt walls looming over the fertile banks of the Tigris, The city walls were built by the Romans, who named the city Amida. Throughout the years, Diyarbakır would be conquered by Persians, Arabs, and the Ottoman Empire. Today, the walled city still retains much of its medieval air, not to mention its street pattern. Keep in mind that many citizens of Diyarbakır are Kurdish-origin Turks.

The Great Mosque of Diyarbakır (Diyarbakır Ulu Cami): This amazing mosque was built in the late 11th century by the Seljuk sultan Malik-Shah I and is one of the oldest mosques in Anatolia. Definitely worth a visit!

Surp Giragos Armenian Church (Ermeni Kilisesi): This Armenian church is located on the same street as the Great Mosque of Diyarbakır and is the largest Armenian church in the Middle East. Built in 1515, this magnificent church used to accommodate 3000 worshippers at a time!

Sülüklü Han: Sülüklü Han was once a caravansary and believed to possess leeches that can cure any sickness. Today, it is a bustling cafe and terrace where you can enjoy traditional Turkish tea and Turkish coffee.

St. Mary Church: St. Mary Church was built as a pagan temple in 1 B.C. and turned into a Syrian Orthodox church in 3 B.C. Today, it is one of the few churches in Turkey where they read the Bible in Jesus Christ's mother tongue, Aramaic.

Diyarbakır Fortress (Diyarbakır Kalesi ve Arkeoloji Müzesi): Built around 4 B.C. by the Romans, Diyarbakır Fortress' long walls are accepted as the longest wall structure after China's Great Wall. It is also a Unesco World Heritage Site. Inside the fortress, you can also visit the Diyarbakır Archaeological Museum, Saint George Church, and Ataturk Museum.

The business and finance capital of the southeast, Gaziantep (also known as Antep), is known for its pistachios and the baklava made from them. It's a very old city, yet only a few bits of its antiquity remain. However, you can still visit some pretty impressive ruins and sites.

Urfa, as it's commonly called, has a rock promontory at its center crowned with an ancient fortress. At its foot is a sacred pool and the reputed birthplace of the Patriarch Abraham. It's a popular place of pilgrimage for Muslims, with a fascinating bazaar and a few fine old buildings. It's also the best base for visits to nearby Harran and the world's oldest known religious site, Göbekli Tepe.

Cave of Abraham (Mevlid-i Halilulrahman Mağarası): This is the historical site where Prophet Abraham is believed to have been born. There are also mosques and a park with a pond. The pond and the fish inside are believed to be sacred. As the story goes, this is also the place where Nemrut tried burning Abraham, but God turned the wood into water and the coals into fish.

Şanlıurfa Castle (Urfa Kalesi): Urfa Kalesi is the ruins of an ancient fortress; it is located just next to the Cave of Abraham and provides a breathtaking view of the site.

Kizilkoyun Necropolis: Dating back 2000 years, this is the necropolis of the Edessa Kingdom, which has Roman tombs, reliefs, and mosaics.

Göbekli Tepe: Göbekli Tepe, built by the nomads in the region, is the oldest religious site known to humans. It is an 11,000-year-old temple complex that was discovered near Şanlıurfa. If you have any interest in history or archeology, you simply have to visit it. Archeologists say, "It changes everything."

Harran: An astounding sight: a warren of beehive-like mud houses rising from the Syrian plain. Harran (a municipality of Şanluurfa) looks like it has been here forever—and it has, ever since the Book of Genesis, at least.

Yet another ancient town has now grown into a modern city with little to show for its long past. Kahramanmaraş (or simply Maraş) has decent hotels if you need a place to stop. It's famous for its ice cream, which is so thick with a binder that you can hang it on a hook for display. Keep in mind that Kahramanmaraş was deeply damaged during the February 6th, 2023, Turkey-Syria earthquakes and is currently under renovation.

This city is one of the most stunning spots in the area. Perched at the edge of a plateau looking out over the Syrian plain, Mardin has several impressive oldish buildings (1300s and later), but the Assyrian monasteries around Midyat in the Tur Abdin region to the east are far older, some dating from the 5th century.

Because it's up in the mountains rather than on the plain, Nemrut Dağı, Adıyaman, Kâhta, and  Malatya belong more to Eastern Turkey than to the Southeast. But Nemrut Dağı, the mountain, and its colossal statues are easily accessible from the cities of the Southeast, so you may want to combine visits to them.
