List of World Heritage Sites in Turkey

Troy (Hittite: 𒆳𒌷𒋫𒊒𒄿𒊭, romanised: Truwiša/Taruiša; Ancient Greek: Τροία, romanised: Troíā; Latin: Troia) or Ilion (Hittite: 𒌷𒃾𒇻𒊭, romanised: Wiluša; Ancient Greek: Ἴλιον, romanised: Ī́lion) was an ancient city located in present-day Hisarlik, Turkey. It is best known as the setting for the Greek myth of the Trojan War. The archaeological site is open to the public as a tourist destination, and was added to the UNESCO World Heritage list in 1998.

Troy was repeatedly destroyed and rebuilt during its 4000 years of occupation. As a result, the site is divided into nine archaeological layers, each corresponding to a city built on the ruins of the previous. Archaeologists refer to these layers using Roman numerals, Troy I being the earliest and Troy IX being the latest.

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.

Xanthos or Xanthus, also referred to by scholars as Arna, its Lycian name, (Turkish: Ksantos, Lycian: 𐊀𐊕𐊑𐊏𐊀 Arñna, Greek: Ξάνθος, Latin: Xanthus) was an ancient city near the present-day village of Kınık, in Antalya Province, Turkey. The ruins are located on a hill on the left bank of the River Xanthos. The number and quality of the surviving tombs at Xanthos are a notable feature of the site, which, together with nearby Letoon, was declared to be a UNESCO World Heritage Site in 1988.

The city of Xanthos was a centre of culture and commerce for the Lycians, and later for the Persians, Greeks and Romans who in turn conquered the region. Xanthos influenced its neighbours architecturally; the Nereid Monument directly inspired the Mausoleum at Halicarnassus in the region of Caria.

Hattusa, also Hattuşa, Ḫattuša, Hattusas, or Hattusha, was the capital of the Hittite Empire in the late Bronze Age during two distinct periods. Its ruins lie near modern Boğazkale, Turkey (originally Boğazköy) within the great loop of the Kızılırmak River (Hittite: Marashantiya; Greek: Halys).

French archeologist Charles Texier brought attention to the ruins after his visit in 1834. Over the following century, sporadic exploration occurred, involving different archaeologists. The German Oriental Society and the German Archaeological Institute began systematic excavations in the early 20th century, which continue to this day. Hattusa was added to the UNESCO World Heritage Site list in 1986.

Mardin (Kurdish: مێردین, romanized: Mêrdîn; Arabic: ماردين, romanized: Mārdīn; Syriac: ܡܪܕܝܢ, romanized: Mardīn; Armenian: Մարդին) is a city and seat of the Artuklu District of Mardin Province in Turkey. It is known for the Artuqid architecture of its old city, and for its strategic location on a rocky hill near the Tigris River.

In February 2000, the Turkish Ministry of Culture placed Mardin and its surrounding cultural landscape on the country’s Tentative List for UNESCO World Heritage nomination.

Letoon or Letoum (Turkish: Letoon, Ancient Greek: Λητῷον) in the Fethiye district of Muğla Province, Turkey, was a sanctuary of Leto located 4 kilometres (2.5 mi) south of the ancient city of Xanthos, to which it was closely associated, and along the Xanthos River. It was one of the most important religious centres in the region though never a fully-occupied settlement.

Letoon was added as a UNESCO World Heritage Site in 1988.
