The existence of numerous caves is inextricably linked to the rugged topography of Crete. People lived in caves thousands of years ago, as evidenced by the prehistoric carvings in the cave Skordilakia by Asfendou. Moreover, today's religious tradition in the caves, which hosts cavernous chapels, is an evolution of the worship of ancient gods inside caves.
Originally, the Minoans worshipped their major deities, such as Eileithyia, the goddess of childbirth, in caves. Later, they placed the birth and upbringing of the king of the gods, Zeus, in the Diktaean and Idaean caves, turning them into important religious centers. During the Byzantine era, caves which according to tradition hosted Saints, such as Saint Paul, Gerasimos and John Xenos, were converted to important ascetic communities. Many pages of Cretan history were also written in the caves of Crete, such as the massacres in the caves of Melidoni, Milatos, Krionerida, Xotikospilios and Tigani at Gramvousa.
Many caves are of very high speleological and ecological significance. Caves with rich decoration which are open to visitors are the Diktaean Cave by Psychro, Gerontospilios by Melidoni and Sfendonis by Zoniana. Besides the caves of religious or historical value, Crete has more than 4.500 mapped caves and sinkholes, available to each experienced speleologist who wants to enjoy their rich decoration and fauna. Areas that host a large number of caves, ideal for cavers, is mount Stroumboulas by Heraklion, the Geopark of Sitia, the Geopark of Psiloritis and Melidoni area in the White Mountains. The three deepest explored sinkholes in Greece are all located in Crete.
The Cave of Marathokefala or Marathospilios is located next to the village of Kynigiana, 29km southeast of Rethymno. In Mylopotamos area, where it is located, several caves have been found.
Just a few meters away from the last houses of the village Samonas, road works revealed a small cave in 1994, with rich décor and a small pond. In order to access the main room a ladder is used.
The cave of Arkalochori, also known as Holy Cave, is situated at the South West side of Arkalochori village, specifically at the south west aisle of Profitis Ilias Church, 400m above sea level. A narrow entrance (0.70cm wide, 1.60cm tall) leads to the interior, where one cannot walk upright due to lack of space.
It consists of two rooms with different levels and relatively rich cave decoration. Both surveys revealed pottery of Neolithic and Minoan era. Specifically, the main use of the cave as a residence focuses on Neolithic period (3650/3500 - 2900 BC) and is was reused as shelter during the Late Minoan (1300-1250 BC) period.
