Since the early Christian years, Crete became a cradle of Orthodox Christianity. This is reflected on the hundreds of religious monuments on the island. Even the struggles for liberation, in most cases, started from the monastic communities.

Religious tradition is very intense in all areas of Crete and is present in everyday life of the Cretans. Crete has an autonomous Archbishopric, separate from the rest of Greece. With thousands of places of worship and dozens of monasteries that have played a special role in the consolidation of Christianity and the struggle against the invaders, Crete is an ideal religious and historic destination.

Since the early Christian times, when Paul the Apostle visited Crete and preached the new religion for two years, the Christian tradition developed through the centuries. Remote places of monastic self-exile, traces of early Christian basilicas, cavernous chapels and painted Byzantine churches are found everywhere on Crete.

Many monasteries played an important historical role during the struggles of the Cretans for liberation. Moreover, Cretan iconography flourished especially in the Venetian Era, with El Greco and Michael Damascenus being the most important representatives.

The first basilicas, temples of a specific architectural type, were founded in the 4th century AD. Their remnants are still awe-inspiring due to their size and imposing appearance.

In Crete about 80 basilicas have been identified. This number indicates economic well-being, since the construction of such large monuments was very expensive. Gortys, Crete's capital till the Arab rule, hosted the largest of those, dedicated to Saint Titus. Its remains are located near the village Mitropoli, while there is a smaller basilica within the archaeological site of Gortys, also dedicated to Saint Titus.

Apart from the basilicas of Gortys, the visitors can see ruins of similar religious monuments at Hersonissos, Fragokastelo, Elounda, Almyrida, Panormos, Goulediana, Sougia, Eleftherna and other parts of Crete.

Paul the Apostle left a great legacy for the future preachers of the Christian faith. His replacement, Saint Titus, soon became widely known for his prominent personality. Today his skull is stored in the imposing church of Saint Titus in Heraklion.

Another important religious figure, who is considered the founder of asceticism on the island, was Saint John the Hermit. John arrived in Crete with 98 other hermits from Egypt and lived in caves, at the site where Azogyres Monastery is located today. Later, he lived alone in caves of Marathokefala and Akrotiri Cape, where a rich ascetic tradition was developed.

Another bishop of Crete, Saint Myron from Rafkos, is celebrated with a splendor in the village Agios Mironas. Holy water gushes in the cave where he lived. Last, during the empire of Decius, ten Christians were beheaded for their faith in Christ. Today, the village Agii Deka (“Ten Saints” in Greek) is built on the site where the martyrs lost their lives.

Pope Alexander V (1409-1410), given name Peter Philagris, came from Crete.

The arrival of St. John the Hermit in Crete was the beginning of a great ascetic tradition that continues to the present day. Hundreds of hermits secluded in the most remote parts of the island, forming ascetic communities that later evolved to thriving monasteries.

A special sample of hermitage is the Catholic Monastery at Akrotiri Cape in the caves of which hermits lived their monastic life away, from worldly pleasures. Equally important were the religious sites of the secluded peninsulas Gramvousa and Rodopos, where several small monasteries developed.

The greatest hermitage of all was the naturally isolated, and impassable range of Asterousia in southern Heraklion. Hundreds of caves from Saint Nikitas to Cape Lithino still host hermits. The Relations between them were so limited that in Agiofarago and Martsalo they gathered only once a year, in cave Goumenospilio and counted how many of them survived each year.

In eastern Crete, the north province of Mirabello is the largest field of asceticism with dozens of small monastic establishments. Here hermits built small monasteries, where they usually lived alone.

In Crete there are more than 800 churches adorned with wonderful frescoes, which depict the evolution of ecclesiastical art from the early Byzantine times to the Cretan School of Painting during the Venetian Era. There are some specific areas with an impressive number of such temples.

Apart from the great religious center of Mirabello, the area of Avdou and Episkopi by Heraklio boasts a large number of monuments of outstanding artistic and religious significance. The region that can be characterized as the largest hagiographic park site in Crete includes the provinces Selino and Kissamos. It hosts dozens of chapels bearing frescoes, painted by prominent artists of their time.

Magnificent samples of hagiography and ecclesiastical architecture are located in many other parts of Crete. One of the most famous monuments is Panagia Kera in Kritsa, while other important temples are Saint Nicolas in Kyriakosellia, Panagia in Meronas, Varsamonero, Panagia Kera Eleousa in Kitharida and more.

During the transition from the worship of Roman deities to Christianity, many of the previous habits were incorporated into the new religion. Devotional caves and Minoan peak sanctuaries continued to serve the worship of Twelve Olympians and were later adapted to the Roman religion, before transforming to Christian temples.

Caves in steep cliffs and canyons are still used as places of worship. In canyons, temples are usually dedicated to Saint Anthony, such as in the gorges of Patsos, Agiofarago, Samaria, Platania, Gallos, Kotsifos. Other well-known cavernous chapels are Saint Anthony at Koudoumas, Hagia Sophia in Topolia, Agia Dynami in Argyroupoli, Saint John by Kapetaniana, Panagia Kera Spiliotissa inAgios Thomas, Saint John the Hermit at Akrotiri and Marathokefala, Panagia Arkoudiotissa at Gouverneto, Saint Andrew at Finokalias, Panagia Spiliotissa in Houdetsi, Santa Fotini in Avdou, and more.

Today, temples have been built on the site of former Minoan peak sanctuaries and serve Orthodox Christianity. Most of them are dedicated to the Holy Cross or the Prophet Elijah. The churches of Christ at the sacred mountain of the Minoans, Youchtas, the Holy Cross on the highest peak of Crete and at Kofinas, Saint Panteleimon at the site of ancient Rizinia, All Saints at Vrisinas and more are very impressive.

Visitors of Crete have the opportunity to admire collections of ecclesiastical art in numerous museums and open exhibitions around the island. Very old icons, priestly vestments, manuscripts, seals and books are some common exhibits.

Well organized ecclesiastical collections are housed in the Byzantine Museum of Chania, the Ecclesiastical Museum of Rethymnon and the Byzantine Collection of Heraklion hosted in the Basilica of Saint Catherine of Sinai.

Important monasteries often house folklore or religious museums with very interesting exhibits. Such collections include the monasteries of Arkadi, Toplou, Tzagaroli, Gonia, Chrysopigi, Preveli, Kalyviani and the Ecclesiastical Museum of Roustika.
