According to legend, Prince Yuri got lost in the forest, he wandered through the forest for seven days and fell on his knees tired, and began to pray to God for salvation. At this time, an old man with a beard long to the ground appeared in front of him, who addressed the surprised young man with the words: “Do not be afraid, child, I am Onufriy, and God has sent me to show you the way.” So Yuri found his way and escaped. Overjoyed by the miraculous salvation of his son, Prince Lugven founded a monastery in honor of this saint at the place of the appearance of the Prince of St. Onufriy, and Yuri himself then brought here from Mount Athos the image of St. Onufriy. Onufriya, in the lower part of which there was an image of Yuri himself, who prays for salvation in the forest. Semeon Lugven, his son Yuri and grandson Ivan donated land to the monastery, villages: Onufrievo, Galovchino, Kolemyanniki, Komarovichi, Gostyn – with the villagers. Then the monastery was patronized by Prince Bagdan Ozeretsky of Drutsky. In 1594, King Zhigimont III handed it over to the Chancellor of the INCL Lev Sapieha. In or about 1630, the monastery passed into the possession of the Basilan Order of the Uniates. Orthodox monks left the lands donated by Lugven. Since 1772, the monastery has been part of the Russian Empire. In 1814 The monastery farm is transferred to the military department to accommodate the military settlements of the Yelets and Polotsk regiments of the 11th Division. Three folvarkas are attributed to the monastery: Pavlovichi, Starino and Sharaevo. The monastery had a library, which in 1823 had 228 books. A Uniate parish from three villages was assigned to the monastery – Slobodka, Selets, Golovchits, where about five hundred believers lived. In the first quarter of the XIX century. in the monastic possessions there were 10436 dessiatines of land, 1325 dessiatines of forest, 3 folwarks, a distillery, 7 watermills (2 of them had cloth mills) and more than 1000 villagers. Onufriyevsky monastery had monks-teachers to teach secular youth. In 1754, Afanasy Martinkevich taught rhetoric to five Basilians. In 1798 Kleshtar supported 15 students and one teacher at his own expense. Russian, Polish grammar, arithmetic, writing, etc. were taught here. In 1839, the monastery returned to the Orthodox, and its church became a parish. The ancient Orthodox church of St. Onufriy has not survived to this day. When at the beginning of the XVII century the monastery was captured by the Uniates, they tried to destroy everything Orthodox. The temple itself was destroyed, erecting a majestic basilica on this site, which has survived to our time, but in a ruined form. Inside the present church, nothing has been preserved from the ancient Orthodox church except the icon of St. Onufriy and another apparently of the same antiquity of the same size and on the same old and on the same old solid board; but the middle part of this icon was cut out by someone and the Kazan Icon of the Mother of God was inserted in the clipping, printed on on paper and covered with a silver-plated chasuble; cherubs from the ancient icon have been preserved only in the upper and lower parts of the board. Other monuments of Orthodox antiquity can be found only in the bowels of the earth: everywhere around the church and still traces of ancient stone buildings are found. There are still many remnants of the Uniate time in the church today; the Uniate residential building has also been preserved. In addition to the ancient Uniate icons, the remains of the old iconostasis of artistic Italian painting and wonderful carvings were located on the walls of the temple. The old iconostasis in the church was replaced in 1909 with a new one of extremely rough and tasteless work..
