These bema doors originally combined carved relief and painting, which has been worn off. They are divided into two sections. In the lower one there are four arches resting on columns which probably framed paintings of prophets and hierarchs. Above the arches, two masks with flowering tendrils are emerging from their mouths. In the upper section there is a representation of the Annunciation, with the Angel on the left and the seated Virgin on the right, figures carved almost in the round within arched frames resting on columns and surrounded by vegetal decoration. On the left door, the Archangel Gabriel is holding an open roll and a bunch of flowers, in accordance with the Western model. On the right door, the Virgin is sitting on a high-backed chair with her hands on her breast, a pose which denotes her acceptance of the Angel's message. At the triangular top of the doors, two winged dragons can be seen. The central slip is covered with a foliate ornament.
