In the second half of the 12th century, a long nave (32 x 8 m) was built, with a west facade with blind arcades and a flat chevet. In the 13th century, the west portal was rebuilt up to date and the nave received perhaps its first ribbed vaults.
A Gothic bell tower-porch was built in front of the nave in the 15th century, which lengthened the church by some five metres. The floor surmounted by a spire is pierced with twin bays, underlined by a cord. Its base forms a marthex.
On each side of this closed porch are two small chapels with vaults decorated with coats of arms and reproducing corner consoles sculpted with grotesque characters.
The 12th century facade is pierced by an ogival portal. The arches fall on the 3 capitals of the torus columns.
The door is flanked by 2 blind arched bays with a zigzag band and diamond points. Around the portal, an inscription: “The French recognize the existence of the supreme being and the immortality of the soul”.
In the 15th century, the nave was doubled to the north. This vaulting was destroyed during the wars of religion and the ribbed vaults were redone in 1872.
The large broken arches which separate the 2 vessels from the nave fall into penetration on large cylindrical piles. On the south wall, a group of 3 columns decorated with large foliage receives the ribs of the vaults. The south side wall from the nave to the chevet was rebuilt with old materials, some of which are carved stones.
The large tracery canopy is followed by 3 Romanesque windows decorated with billets and diamond points.
The choir with a flat apse is lit by a Romanesque triplet with small columns and polylobed arches. It is a provision that we find rather outside the churches.
Outside, these 3 windows have no columns and are surmounted by a cornice shaped like a whistle on brackets and a large half-moon opening.
In 1996-1998, a restoration campaign brought to light mural paintings and a funerary liter, a striking portrait of death.
Special features to see also: a very beautiful stone pulpit and wrought iron railing from the 19th century as well as an oil on canvas, "Crucifixion", from the beginning of the 19th century.
