The first internal painting of the church began in 1748-1749. Bishop Olsavszky gave the commission to István Vörös, a painter from Kassa. The decorative paintings he made were painted over at the end of the nineteenth century. However, during the renewal under the leadership of József Boksay in 1940, several of its elements were restored, or repainted. The monumental “panneau” depicting the Cult of the in Hungary, which decorated the wall of the Sanctuary, was created at this time by Manó Petrasovszky. In 1748, bishop Olsavszky commissioned a Greek master craftsman, named Constantine, to create the iconostasis of the shrine church. He completed the thirteen meter tall and six meter wide work, richly decorated with carvings, in less than eight months. The painters of the earliest pictures are unknown. In 1785, the basilian painter Mihály Spalinszky was entrusted with the creation of the icons of the iconostasis. Most of the icons he painted were removed by the Spisák brothers, who created the new pictures in 1896, and only five remain. The Saint Icon was placed above the central beautiful gates of the iconostasis. The new holy altar on the left side of the nave was finished with the assistance of the Franciscan masters at Pécs in 1946. The design allows the pilgrims to approach the Saint Icon from the courtyard of the church and without disturbing the services in the church. The new pilgrimage church is able to accommodate much larger numbers of pilgrims. Under the guardianship of the Basilian monks, the Saint Shrine has become the most important pilgrimage site in Eastern Hungary. This made the nineteenth-century expansion possible and necessary. In 1856, the church towers were raised one level, and in 1896 the interior of the church was renewed.
