About 2km outside the village of Melidoni is this stunning cathedral-like cave, an evocative underworld of stalactites and stalagmites. A place of worship since Neolithic times, it also carries heavy historical significance as the site of a massacre in 1824 during the Turkish occupation. Here 370 villagers and 30 soldiers sought refuge from the Ottoman army; after a three-month siege, the Turks lit a fire and asphyxiated the people inside, including 340 women and children.
Wear decent walking shoes, as the cave is poorly lit and the ground uneven and slippery in places. You’ll need to descend 70 steps into the cave. Also bring a sweater: at 24m below ground, the temperature never gets above 18°C.
