Listed as a historic monument, it was built in the 15th and 16th centuries. Dominating the village is this important one
stone construction with a sandstone base and
an 8th century bell tower. The architecture of the ship is
remarkable, especially for its vaults and chapels.
The first church of Agnez, whose date of construction is unknown, was destroyed in 1475 by the French troops of Louis 12. Only the tower and the choir remain. But traces of the old ship are still visible at the foot of the tower. The 15th century bell tower was raised around 1632 and topped by a stone spire. The building was then restored between 1842 and 1845 by architect A. Grigny. The interior of the church is decorated in Gothic style.
The tower has a defensive appearance, which leads us to believe that it served as a lookout post during military tensions. Indeed, we can see a crenellated balustrade at the top of the tower protecting the walkway from enemy fire. Loopholes have also been created in the front of the tower so that spectators can watch without being seen. They could also shoot their attacker from cover.
To complicate and delay the siege of the church, diagonal buttresses are placed on the walls of the tower. We can also note that the tower does not have large windows that could facilitate the penetration of attackers into the church. The only openings in the tower are the abat sounds that allowed to spread the sound of the bells, used in certain cases to warn the population of an attack.
