The cathedral is very large and glorious in its beauty and proportions and is one of the most beautiful cathedrals in France. The two bell towers look like fortresses with almost 90-degree sloped roofs covered with stone and ending with a rooster. This design is apparently very typical of the surviving churches from the days of William the conqueror in Normandy. Instead of a typical rose window on the façade, there is a stained glass in the shape of an arch. Inside the cathedral is unlike others: early gothic still affected by Romanesque with circular shape arches supported by heavy pillars with bas-reliefs of monsters, animals, diamonds, and baskets around the contour. Baroque pulpit in the middle is very out of place. Second floor arches are early Gothic, with pointed tops. In some chapels you can find 13th-century original stained glass, some have 19th-century stained glass. At the South gate you can see very light colors of the 15th-century frescoes of Trinity and annunciation – all that’s left of the frescoes that must have at one time covered all the walls of the cathedral. Chapels around and behind the choir have Renaissance painted walls and stained-glass windows with beautiful floral motifs. Above the altar, on the ceiling, if you know where to look, you can see very old and barely preserved frescoes of saints that definitely have Romanesque manner of painting. The altar is impressive in its architecture: 3 rows of pointed arches with rosettes carved out of stone and a small organ above baroque choir. Underneath the altar there is a crypt which is all that remains of the original church. The crypt has well-preserved 15th-century frescoes of angels above each column and in the niches.

Bayeux was the first city liberated in 1944 by the allied troops and was not bombarded. This is by far the reason the cathedral is so well-preserved and has all of its original stained glass.
