In 1873, the abbot of the skete, Elder Hilarion, suffered from a prolonged and severe illness, which led him to consider the necessity of creating a well-equipped hospital for the sick brethren. Father Hilarion bequeathed to the monastery treasurer, Father Flavian, his spiritual son, to build a new hospital. For this purpose, with the consent of Elder Ambrose, he transferred about 30,000 rubles, collected from the skete's savings and donations from monks and voluntary novices.

After the death of Elder Hilarion in 1874, a new two-story hospital with a church dedicated to St. Hilarion the Great was built outside the monastery walls. During the Soviet era, the church was closed. After the revival of the monastery in 1991, the church was consecrated, and in the 2000s, frescoes were painted and an iconostasis was installed.

Currently, the church of Hilarion the Great conducts baptismal sacraments and holds discussions between pilgrims and the spiritual fathers of the monastery.
