The temple is of a cross-like shape inside. It is divided into three parts by the arcades of columns, impressing by the riot of color, painting, lines and shapes, verges and stages, deepness of the expanse. The Cathedral is painted and decorated with icons and paintings related to the history of the monastery and the events of the life of Our Savior. Those are the miraculous healing of Philip, a born blind brother of a landlady Goyska in 1597; the transference of the wonder-working Icon from the castle of Goyska to the Pochayiv hill; the transference of a monk to the abode from the Turkish captivity; the resurrection of a dead baby; a concussion by demon of Firley’s wife; Count Pototski and his coachman, etc. And all that became closely linked with this land – Volyn, with this holy hill, so naturally combines with Evangel stories known to each believer: Jesus Christ and a penitent sinner; Resurrection of the widow's son at Nain; Christ in the house of Marpha and Maria, etc. The Orthodox Symbol of Faith - gold letters from the left to the right. Like the completion of painting, the large image of the beginning of the history of abode: the appearance of the Mother of God in a column of fire.The Cathedral was painted at the beginning of XIX century by Lviv artist Luka Dolynskyy, and sometime later, in 1874 (after fire) the painting was renovated by Lavra’s painters together with academician Vasilyev. The finishing work was made by sculptor Polievskyy. The iconostasis was made under the project of academician Nesterov. It is embellished with thirty three icons. Two churches are settled upstairs in two aisles: a church in honor to Saint Blessed Prince Aleksander Nevskiy to the left and a church in honor of Saint Nicholas Wonderworker to the right. The Divine Liturgy is served there only during the Easter Week. They were consecrated in memory of the visit of the monastery of Nikolay I and Aleksandr II. The Cathedral enchases two Lavra’s relics – the healing God Mother’s Footprint and Her miracle-working Icon.
