Over several centuries of construction, the image of the cathedral changed, multiplying several architectural styles in its appearance: the 11th century brought the Romanesque direction, the 13th century - Gothic motifs, and the 18th century gave Baroque luxury. There is a legend that looking at the magnificent facade of the Cathedral, Wagner found inspiration for one of his works. A giant staircase of 90 steps leads to the main western faç ade. According to legend, the one who, climbing the stairs, counts an even number of steps is a righteous man, and an odd number is a sinner.→
