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.
