On the rock where Paliokastro was built, at the southwest end of Voidokilia Bay, you will see a cave. It is the mythical cave of Nestor, son of Neleus. This is where the royal cattle were kept. According to myth, Hermes hid the 50 cattle stolen from Apollo in this very cave. There, Heinrich Schliemann located finds which dated back to Nestor’s times, proving the early existence of life in the area. The cave is full of stalactites.
