The village changed location and name many times since the earliest record of its existence in
Mycenaean times. The area of Longanikos has been identified with the ancient village of
Belemína (), documented in ancient writings by Pausanias over 1800 years ago. The current name has been documented in writings as far back as
Stefano Magno in 1453. It is believed that this area has been inhabited since
Neolithic times, and much later served as a front-line military outpost for the powerful Spartan city-state. As a result of its geographical position between the 3 prefectures of Messinia, Arcadia, and Laconia and because of the morphology of the ground where Taigetos and Parnonas converge without connecting, thereby creating the Laconian valley of Eurotas, Longanikos has served as a key transit point for the movement of people and armies in the Peloponnese. It had also served as a military staging area and rampart for the state of Sparta. The town is mentioned as
Longanik in the
Seyahatnâme of
Evliya Çelebi which he visited in 1668. He mentions that out of 500 houses only 100 are inhabited as the rest either died because of the recent plague outbreak or fled to the mountains. Çelebi also mentions that the Muslims of the town are converts from the Greeks of the town and that there was only 1 mosque and 11 churches. He also adds that the women of Longanik were producing silk. Today the village of Longanikos also includes the settlements of Vergadeika, Kiparissi, Giakoumeika, and Foundeika. It is nestled along the green slopes and fir-covered mountain range of Mt. Taigetos and one can find stone houses, natural springs and fountains and forest roads that lead to the highest points of the mountain (Koutouni, Limna). Nearby one can also find some fountains that feed the Eurotas valley and the historical monasteries of Rekitsa and Ampelaki, close to the Arcadian border. ==Economy==
