The Anatolian Roads Project
This site is dedicated to research in the field of the Roman road system located in ancient Anatolia, present-day Turkey. The site is sponsored by the History department of Wisconsin Lutheran College under the direction of Dr. Glen L. Thompson and by the Asia Minor Research Center under the direction of Dr. Mark Wilson. The Anatolian Roads Project (TARP) is a work in progress and thus will be updated and improved as time goes on.
