Head to the Kyklopas (Cyclops) Cave near the monastery of Evaggelistria, full of stalagmites and stalactites. Discovered in 1893, the cave boasted a collection of ancient artefacts such as utensils and vessels, suggesting that it was a place of ritual or worship in antiquity. There’s even an altar with evidence of fire and bones, now all covered by material from the stalagmites. The inner chamber features a small lake.
