The geographer Strabo located Antandrus in the Troad on the southern flank of Mount Ida, east of Assos and Gargara, but west of Aspaneus, Astyra, and Adramyttium. The first clue which led to its rediscovery in modern times was found by the German geographer and Classical scholar Heinrich Kiepert in 1842. He found an inscription relating to Antandrus in the wall of a mosque at Avcılar. Returning in 1888, he found a further inscription at Avcılar and, due to the discovery by locals of many Greek, Roman, and Byzantine era coins in the vicinity of a nearby hill called Devren, he was also able to locate the acropolis of Antandrus on this spot. The British archaeologist John Cook surveyed the site in 1959 and 1968, discovering further evidence of a Greek settlement.
