The monastery Dohyar is dedicated to the holy archangels Michael and Gabriel. The monastery is situiated in the south-western part of the peninsula, between the monasteries of Zograf and Costamonit, on the steep hillside by the sea.

The monastery was founded in the second half of the X century by a saint named Ephthimius, a disciple of the Monk Athanasios of Athos, at first it was named in honor of St. Nicholas. Saint Ephthymius was in charge of the pantry in the Great Laura (dohiyarkeeper — kelarkeeper), hence the name of the monastery. According to the legend, during the construction work, which was carried out to expand Dohyar at a later time, the monastery ran out of funds, and the Mother of God discovered to one young novice that on the island of Longus, where the monastery had real estate, near some ruins buried treasure. For the treasure with the young novice two older monks were sent. Huntered unearthed treasure, they became mad with greed and decided to kill the novice to take possession of the treasures. But the young man was saved by the archangels Michael and Gabriel and immediately transferred to the monastery church. The treasure was recovered, and the monastery after this incident was renamed in honor of the two holy archangels. The young novice later took of monastic vow with the name of Barnabas and later became its abbot.

In 1560, a priest from Adrianople, named George, was healed from a serious illness, immersed in the source of the Holy Archangels, which is located on the territory of the monastery, and in gratitude bequeathed his property to the monastery. Water from the source of the Archangels Michael and Gabriel is still used as a saint.
