Ancient Messene lies on the slopes rising up to the summit of Mt. Ithomi, close to the modern village of Mavrommati. The current remains date from the Classical period although the ancient city existed even in Archaic times. The Classical city was founded in 370 BC. The spectacular Sanctuary of Asklepios lies close to the agora. In front of the Temple stands a large hypaethral (open air) altar for sacrifices. Other finds include the odeon, a sebasteion and a fountain.
