Christ is portrayed within mandorlas, while two tall angels address the apostles to show them the celestial vision.

Apart from these two main subjects, the sculptors portrayed scenes of everyday life, such as hunting, not avoiding to underline hardships and painstaking labour.

The interior of the nave is covered with three domes, a transept of great length with lofty towers over the north and south ends, and an apsidal choir with four chevet chapels.

At the crossing with the transept, is a larger dome over pendentives, which has replaced the original one destroyed in the Protestant siege of 1568.

Once lighted by two lantern towers, the transept has maintained only the northern one (Abadie also modified it, and moved the medieval sculptures to other locations), characterized by several orders of mullioned windows.
