Troy (, Hittite: 𒋫𒊒𒄿𒊭 Truwiša) or Ilion (, Hittite: 𒃾𒇻𒊭 Wiluša) was an ancient city best known as the setting for the Greek myth of the Trojan War. It was located at Hisarlik in present-day Turkey, south-west of Çanakkale and about miles east of the Aegean Sea. In Ancient Greek literature, Troy is portrayed as a powerful kingdom of the Heroic Age, a mythic era when monsters roamed the earth and gods interacted directly with humans. The city was said to have ruled the Troad until the Trojan War led to its complete destruction at the hands of the Greeks. The story of its destruction was one of the cornerstones of Greek mythology and literature, featuring prominently in the Iliad and the Odyssey, and referred to in numerous other poems and plays. Its legacy played a large role in Greek society, with many prominent families claiming descent from those who had fought there. In the Archaic era, a new city was built at the site where legendary Troy was believed to have stood. In the Classical era, this city became a tourist destination, where visitors would leave offerings to the legendary heroes. Archaeological excavation of the site began in 1871. Heinrich Schliemann and Frank Calvert excavated the site of the classical era city, under whose ruins they found the remains of numerous earlier settlements. Several of these layers resemble literary depictions of Troy, leading some scholars to conclude that there is a kernel of truth underlying the legends. Subsequent excavations by others have added to the modern understanding of the site, though the exact relationship between myth and reality remains unclear and there is no definitive evidence for a Greek attack on the city. The archaeological site of Troy consists of nine major layers, the earliest dating from the Early Bronze Age, the latest from the Byzantine era. Each of these layers has sublayers for a total of 46 strata. The mythic city is typically identified with one of the Late Bronze Age layers, such as Troy VI, Troy VIIa, or Troy VIIb. The archaeological site is open to the public as a tourist destination, and was added to the UNESCO World Heritage list in 1998. Name In Classical Greek, the city was referred to as both Troia () and Ilion () or Ilios (). Metrical evidence from the Iliad and the Odyssey suggests that the latter was originally pronounced
