Abstract

The current state of two 16th century masonry churches were studied after being damaged during the 2017 earthquake in Mexico. The two complexes being analyzed are part of the World Heritage Site “Ruta de los Conventos”: the Convento de San Guillermo Totolapan, in the state of Morelos south-east of Mexico City, and the Huaquechula Monastery, in the state of Puebla south of Mexico City. These buildings are representative of the architectural model adopted by the first missionaries who evangelized the indigenous populations in the 16th century. The churches were constructed circa 1535 and 1548, respectively. The history and cultural significance for each project is researched in coordination with the stakeholders, along with the contrasting structural systems and any known previous interventions, historic and contemporary. The damage inflicted to the two churches due to the most recent earthquake (2017) is critically analyzed, specifically focusing on inherent defects of the existing materials, the variation in construction methodologies and the impact of contemporary interventions such as the use of reinforced concrete and structural steel following previous earthquakes. Potential repair methodologies are discussed in order to mitigate future damage to the structures. Discussions include the importance of using compatible materials along with appropriate repair procedures and the need for ongoing maintenance of these important heritage structures.
