Aristomenis is a hilly village, situated at an altitude of 354 meters above sea level of Messinian Bay. It belongs to the municipality of Messini and is 35 kilometers away from the city of Kalamata . About 350 residents live there and are occupied with farming as the main products of the region are figs and olives.
Parts of Aristomenis are the settlements of Choreftra and Sarakina, while the main church of the village is dedicated to Saint John the Theologian.
Aristomenis was called Moustafapasa until 1871 and took its ancient Greek name by Aristomenis, leader and hero of Messenians during the Second Messenian War (685-668 BC).
At short distance from Aristomenis and at southeast of the village Kefalovrysso a mycenaean small vaulted tomb was accidentally found in 1998 during the road construction in Paliomilos, dating back to around 1500 BC. The most important element of the revelation of this tomb is its form as it was kept intact.
