The present paper aims to analyze the building technique of the Stoas of the Asklepieion at Messene, which were built in the beginning of the 2nd century B.C., and to understand a part of the Hellenistic building techniques of this region. The optical refinement of the crepidoma of the Stoa and some other unknown techniques which were employed in the Messenian Stoa confirm us that continuous endeavors of technical renovation were taken place by the Hellenistic craftsmen, following the tradition of the building techniques of Greek architecture that date back to the 4th century B.C.
