Kardamili (variously transliterated as Kardamyle, Cardamyle, Kardhamili, and Kardamyli, and sometimes called "Skardamoula", especially on old maps) is a town by the sea in Messinia near Kalamata.
Kardamili sits at the foot of the Taygetus mountains on the coast of the Messenian Bay. Much of the town sits on the remnants of a prehistoric lava flow, the remains of which can be seen as the lava rock outcrops which separate many of the local beaches from one another. The local beaches stand out from those in other areas of the world for the remarkably round stones of which they are made up. Nowhere else in the world is it possible to find smooth, often spherical stones on a beach, and the phenomenon has been subject to multiple studies done to find the cause of such a unique occurrence.
The area is filled with beaches: Ritsa, Belogianni, Salio, Tikla, Amoni, Santava. The older town includes a mediaeval castle and outworks, and the imposing church of Saint Spyridon. Many of the buildings of Old Kardamili, also known as "Pano Kardamili", or "Upper Kardamili" were built by the Venetians and feature a mix of traditional Greek and Venetian design.
