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 Velamini (Velmini), 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, Logganikos has served as a key transit point for the movement of people and armies in the Peloponese. It had also served as a military staging area and rampart for the state of Sparta.

Today the village of Logganikos 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.
