The ancient cathedral dominates the castle grounds. Centuries of reconstructions have left the building a conglomerate of different styles. The greatest reconstruction, ordered by Bishop John Telegdy, gave the cathedral a predominant early Baroque look. It was during this reconstruction that the vertically divided building complex was created. László Ádám Erdődy, Bishop and Chancellor of Hungary, finished off the reconstruction by ordering excellent ornamentation, which is considered the greatest example of Baroque ornamentation in Slovakia. Sts. Emeram, Andrew Zorard, and Benedict of Szkalka are patron saints of this cathedral. The 2014 saw an end to a series of reconstructions going on since 2005, which brought a number of important discoveries. The last discovery was a late Gothic fresco depicting the Death and Coronation of Virgin Mary, located in the bottom navel. The fresco has since then been restored and made accessible to the public.
The fresco has been hidden out of sight for several centuries. It was painted sometime at the turn of the 14th and 15th century. It was probably a part of a Marian altar. It depicts a dying Virgin Mary surrounded by the apostles, among whom Peter, holding papal insignia, is discernible. Another section of the fresco depicts Virgin Mary’s Coronation. The upper part of the work shows the Veil of Veronica with the imprint of Jesus’s face held by angels.
The relief is a part of the 1662 Szelencseneyi altar located in the upper navel. According to the signature, its creator is the younger Hans Pernegger (1603 – 1662), the most prominent member of a large Salzburg stone sculptor family. Three main figures dominate the composition. Joseph of Arimathea with Nicodemus are lifting the body of Jesus and placing it into an open sarcophagus. Weeping Virgin Mary, Magdalene and other figures are in the upper background part. What is interesting is the presence of torture devices on the ground. Another notable feature is the pyx-shapped container decorated with the motif of playing children.
