This building has three distinctive phases which illustrate the medieval transformations.
From a first Romanesque construction there remains a section of wall with a small blocked bay and vestiges of the cornice with cornices on the first bay to the north of the nave as well as an arch and two bases of leaning columns on the facade. The beginning of the Gothic is visible to the north and east. On the north side, a very beautiful twin bay, with narrow lancets, still has semicircular arches inherited from the Roman
Its foliage decoration evokes the beginning of the 18th century. The apse bay, in third point, already has tracery and testifies to a later phase.
In the attic, traces of arches on the walls prove that the 13th century vaults were higher than those of today.
In the 15th century, the building was taken over, retaining only these few sections of walls.
The new construction, more homogeneous, appears as a rectangle supported, on each corner and on the long sides, by powerful buttresses. It is covered with ribbed vaults with prismatic ribs and emblazoned keys. The facade opens with a flamboyant Gothic portal, with an archivolt with hooks and fleurons, and its gable is crowned by a small quadrangular bell tower. Pointed arch bays, with flamboyant tracery. The north wall is representative of the three stages of construction of the building: the west bay is partly Romanesque, the east bay dates from the 13th century and the middle from the 15th century, while to the south the wall is consolidated by powerful buttresses.
At the very end of the 15th century or the beginning of the 16th century, they wanted to open a side chapel on the first bay which was never continued, as the waiting stones show.
On the reverse side of the facade, the bell tower required the construction of powerful massifs between which is placed a gallery covered with a long vault pierced by a large oculus.
In Saintonge where Romanesque churches are the majority, this church is one of the rare examples of accomplished Gothic construction.
