Historic and therefore older adobe buildings, because of the nature of their construction, always suffer severe damage during major earthquakes. This paper describes the rehabilitation of an almost 100-year-old adobe church using welded-steel mesh as a stability retrofit measure. The objectives of the rehabilitation were to create a structure capable of surviving a strong seismic event and to do so without damaging the original dynamics and architectural character of the building. The church has 7.9-m-high lateral adobe walls and a timber-truss roof system. The slenderness ratio of the walls is 10. Since its rehabilitation, this church has successfully withstood 16 earthquakes with magnitudes from 4.1 to 6.0.
