5 23 February 1828 earthquake on churches. (A) Photograph
of Autre-Eglise church showing the gable end formed on a sub-foundation of stone before the
earthquake with its upper part rebuilt in bricks after the earthquake, as noted in historical sources
(see the inscription 1830 on the small white stone above the door, which indicates the date of the end
of the repair work). The cramp irons visible on the tower are also repairs following the earthquake.
(B) Photograph of Marilles church tower, damaged by the earthquake. Cramp irons indicated the date
of the end of the repair work (1831). (C) Photograph of an opening in the nave wall of Petit-Hallet
church, repaired in 1829, with cracks in the masonry above the opening. All the openings in the nave
show the same kind of disturbance. One can also observe the introduction of a small stone to prevent
the keystone from falling. (D) Photograph of an opening in the nave wall of Jauche church with
double cracking of the upper-level masonry, as well as cross-shaped cracks. One can also observe
small spiral cramp irons to prevent rocking of the keystone.
