Kalamos is a huge rock that sits on the southeastern side of Anafi island. Kalamos rock, which is also known as the "Scariest rock in Europe", is the second biggest monolith in Europe after Gibraltar. Being 460 m. high, Kalamos is arguably the most impressive natural attraction in Anafi and also a popular climbing spot. On the top of the rock stands Panagia Kalamiotissa church, a beautiful whitewashed chapel, built in 1715. This chapel offers a marvelous view to the island and it is the perfect spot for sunset gazing.
