By far one of the top things to do while in town is visit Troy. The discovery of ancient Troy (the city thought to be the site of the Homeric legend of the Trojan Wars) was mostly thanks to amateur German archaeologist and treasure hunter Heinrich Schliemann, who began digging here in 1871.
Later, archaeologists working here have excavated not just the one famed city of King Priam, who fought the Greeks in a long 10-year war (as told in Homer's Iliad) but several layers of different settlements that flourished here over a course of 2,500 years (from 3000 BC to AD 500).
