Abstract Many churches, temples, and mosques stand as cherished heritage structures, embodying the rich cultural essence of communities worldwide. Monitoring and maintaining these structures often demand unique considerations due to their distinctive features and materials. Provided in this paper is a review of sensors used in the SHM of 45 historic places of faith through discussions of sensor benefits, limitations, rational, and deployment locations across different building types. This review is contextualized via a case study of the Cathedral of the Immaculate Conception in Saint John, NB, Canada. Following a brief history of the cathedral, complications due to previous conservation efforts are discussed and the cathedral’s present state is described. Then, the sensor selection process for phases one and two of a cost-effective SHM implementation is presented. Finally, the staging and timing of sensor installation is detailed. This SHM system is expected to assist in timely damage detection and condition-based maintenance, minimising the cost of interventions. © 2024 The Authors. Published by ELSEVIER B.V.

Introduction Structural health monitoring (SHM) is of vital importance in historic places of faith, acting as an early warning for structural failure, a means of analysing the success of interventions, and guidance for targeted conservation.
