Where Troy Once Stood is a 1990 book by Iman Jacob Wilkens that argues that the city of Troy was located in England and that the Trojan War was fought between groups of Celts. The standard view is that Troy is located near the Dardanelles in Turkey. Wilkens claims that Homer's Iliad and Odyssey, though products of ancient Greek culture, are originally orally transmitted epic poems from Western Europe. Wilkens disagrees with conventional ideas about the historicity of the Iliad and the location and participants of the Trojan War.
