In Tyniec all has its history. The history of the altar in the centre and banister started when in XV Abbot Maciej of Skawina undertook the building. He pulled down three walls of the church, levelled the area and developed the temple towards the north and the west. Today we can see Gothic windows and two southern ones that preserved stone traceries. There are two Tyniec chalices in Tarnów, choral books, the first portraits which represent the former abbots: Mścisław in Antiphonal of his foundation, Maciej of Skawina in the painting from the altar in Tuchów (today in National Museum in Cracow).

Gothic in Tyniec with its pointed arches must have been beautiful while the historian Jan Długosz declared the abbey the 'gem of the motherland'. Today it would be defined as 'late Gothic'. At the beginning of XVI century a lower part of one of the windows was walled up to paint a fresco of huge size. We can admire it above the stalls on the southern side of the church. It represents the Obeisance of the Three Magi. It is worth paying attention to the figure by Blessed Virgin Mary's knees. A bit lower, currently invisible (because it is hidden behind the stalls), the inscription STANISLAVS which identifies this figure as an image of Abbot Stanisław Baranowski  (1512-1526).
