The sculpture of St. Judas Thaddaeus was made by Franciszek Feeg in 1776. The funder of the high altar, and therefore its sculptural decoration, was Jan Joanelli of Tolvano. The altar and its sculptures are examples of so-called Rococo of Spiš – a style that gradually developed from the 1740s and was characterised by exceptional decorativeness of means of expression. The creativity of these artists from Kežmarok was the culmination of that style St. Judas Thaddaeus, also called the brother of James, belonged to the group of apostles. Together with St. Simon, he suffered a martyr's death in Persia around the year 80.
