Overview

The Cave of Oliaros, also known as Antiparos Cave, is the most popular tourist attraction on the small Cycladic island of Antiparos. It sits more than 100 metres above sea level and was first explored in the 15th century.
Antiparos cave has a rich history, having been used both as a refuge and a place of worship.
The entrance to the cave is home to what is believed to be the oldest stalagmite in Europe. It’s around 45 million years old! A more recent addition to the cave’s entrance is the Agios Ioannis Spiliotis, a white chapel that was built in the 18th century.
