[1] Antoni Mironowicz associates the beginnings of the sanctuary with the cult of the miraculous icon of Christ the Savior, which was particularly venerated already in the 13th century in the church in nearby Mielnik.

[2] According to local tradition, during the Tatar invasions, the monks taking care of the icon were supposed to hide with the holy image in the surrounding forests, and eventually found their way to Góra Grabarka.

[3] The same monks were to initiate a new period of worship of the miraculous icon, which was expressed in giving special importance to the celebrations associated with the feast of the Transfiguration of Jesus on August 19.

In his opinion, information about the existence of a temple with roots dating back to the Middle Ages, in the light of documents, can be considered as having more in common with legends than with historical truth.

It caused panic among the city's inhabitants, who began to leave en masse, hiding in the surrounding forests until the epidemic ended in winter.

[5] This event should be associated with the establishment of a chapel and a cult center in Grabarka, initiated by the Uniate metropolitan of Kiev and abbot of Supraśl, Lev Kiszka.

It was also mentioned that the chapel had the privileges of indulgences from the Holy See, which means that even then Grabarka was an important pilgrimage center, and the water from the stream flowing through it was considered miraculous.

[9] In 1948, an Orthodox parish was established at the monastery, which included the villages of Grabarka, Szumiłówka, Oksiutycze, Pawłowicz, Homoty, Szerzenie and Hałasówka.

[9] In 1956, work was completed on the construction of a winter church dedicated to the Icon of Our Lady "Joy of All Afflicted" with a two-story residential building adjacent to it from the west.

The interior of the chapel received a new - referring to the traditional - design by Adam Stalony-Dobrzański and Jerzy Nowosielski, professors of the Krakow Academy of Fine Arts.

[13] In the years 1977–1981, a new brick monastic house was built, with a spacious refectory church dedicated to the Dormition of the Mother of God.

In addition, Orthodox Christians make pilgrimages to the August celebrations from, among others, Sokółka, Czarna Białostocka, Hajnówka, Bielsk Podlaski, Drohiczyn, Mielnik, Siemiatycze, Grodzisk, Jabłeczna and Warsaw.

The importance of the Holy Mountain of Grabarka as a pilgrimage center increased in the 1980s to such an extent that at the end of the decade several tens of thousands of people participated in the celebration of the Transfiguration of the Lord.

The corners of the walls, window and door frames were covered with bas-reliefs depicting various images of the cross (author Wiaczesław Szum).

[25][26] After completing the renovation, the church was solemnly consecrated on May 21, 2017, by Metropolitan Sava,[27] assisted by hierarchs and numerous clergy from Poland and Ukraine.

[29] Holy Mountain Grabarka was visited (on the feast of the Transfiguration of the Lord) by the incumbent presidents of Poland - Bronisław Komorowski (2011, 2014) and Andrzej Duda (2015).
