Troy was located in present-day Turkey at the mound now called Hissarlik, about 4 miles from the mouth of the Dardanelles.
Also known as Ilium, hence the Greek epic set during the Trojan War is called The Iliad, Troy was destroyed at the end of that war (c. 1200 B.c.).
It was first excavated by Heinrich Schliemann in 1871.
