While the Trojan War is unlikely to have happened exactly the way Homer's writings describe it, a city fitting the description of Troy near the Dardanelles was destroyed at about the time Homer's story references. Ancient Greek and Egyptian records also reference a place very like the city described.
In 1868, Heinrich Schliemann, a wealthy German businessman, helped fund English archaeologist Frank Calvert's excavations on a hill in Turkey. They found successive layers of destroyed prehistoric cities, indicating a series of wars and sieges that are likely to have shaped the core of the story of Troy. Archaeologists are still reconstructing the different layers of the site, but they have matched the site to many elements described by Homer, and as of 2015 are relatively confident in calling it the basis of the story.
