013. Saint-Martin-le-Vieux. The south wall of the Romanesque nave. The large bay with a lowered centering was probably added in the 16th century, during the building of the double belfry. On the right of this large bay, the centering of the small Romanesque bay is carved in a granite block. Photo by Alain Dermigny. [Alain-004]
014. Saint-Martin-le-Vieux. The south wall of the Romanesque nave and its door, with its lowered centering and its abutments with chamfered edges. The small bay on the left is also Romanesque. The masonry of the walls is made of irregular blocks of schist and granite. Elements of opus spicatum (fishbone masonry) are visible, a proof the south wall is the oldest part of the church. Above the door, the little trefoil bay was probably added in the 16th century, during the building of the belfry. Photo by Alain Dermigny. [Alain-005]
