The Monastery of Great Lavra () is the first monastery built on Mount Athos. It is located on the southeastern foot of the Mount at an elevation of . The founding of the monastery in AD 963 by Athanasius the Athonite marks the beginning of the organized monastic life at Mount Athos. At the location of the monastery, there was one of the ancient cities of the Athos peninsula, perhaps Akrothooi, from which the sarcophagi of the monastery that are in the oil storage house come. The history of the monastery is the most complete compared to the history of the other monasteries, because its historical archives were preserved almost intact. It is possible that the study of these archives may contribute to the completion of the knowledge of the history of other monasteries, whose archives were partially or completely lost.

This led to the growth of the monks from 80 to 120. Later history The building project, according to the biography of Athanasius the Athonite (11th century), began with the protective wall and continued to the church and cells. After Athanasius' death, the monastery continued its operation normally. The emperors favored its development and during the 11th century there were 700 monks, while smaller monasteries had been ceded to Great Lavra. In the 14th century the monastery suffered, like all the other monasteries of Mount Athos, from Spaniards from the crown of Aragon and other pirates. Additionally, the Russian pilgrim Isaiah confirms that, by the end of the 15th century, the monastery was Greek. The result of the crisis was the formation of a peculiar way of monasticism, the Idiorrhythmic Way, despite the objections of the official Church and the emperors. In 1574, the Patriarch of Alexandria, Sylvester, helped and the monastery operated again under cenobitic monasticism, but soon the
