The high octagonal tower of the bell tower consists of two floors. The first is embellished on each side with two high blind bays. The second finished in the Gothic period is added by eight large windows. The inner curve of each is cut into small lobes reminiscent of the Moorish style.
During the construction of the facade, the nave was shortened by one bay. In the 14th century ogival style, the arched portal with arches is accompanied by a trefoil window underlined by a checkered cornice.
The square chevet has preserved in the masonry old parts of the semi-circular chevet of Romanesque origin: remains of arcades on columns with capitals, remains of cornices and windows.
The old bay in front of the choir is remarkable for the quality of the sculptures of the Romanesque capitals. One represents a shrine on an altar guarded by two figures. According to C. Connoué, it is an original subject for Saintonge which would have its similar in the church of Notre-Dame-de-Soulac (Gironde).
The shrine represents a church whose two-storey bell tower has a conical roof like that of the Abbaye aux Dames in Saintes or closer to Rouffignac, Nieul-Ie-Virouil. The scene is framed by two large chandeliers, furniture that is rarely represented in Saintonge sculpture.
On another capital, Adam and Eve are represented after the original sin in silly niches drawn by small trees, including that of Good and Evil.
Another shows birds in leaves, a subject that is also treated in the church of Grézac or in that of Jarnac-Champagne.
Outside, the Romanesque chevet is punctuated by engaged columns of decreasing section.
