On March 4, 1751, the San Casimiro earthquake destroyed the city of Santiago de Guatemala once more. The church roof of the Society of Jesus complex fell to the ground, forcing the Jesuits once again to ask for help from the parishioners to rebuild. Once again, the building was among the most beautiful in the city when the repairs were completed. In fact, a period of prosperity began after the San Casimiro earthquake, as the city saw major improvements such as street embellishment and the introduction of a tap water system. A new City Hall was built, and on July 17, 1753, work on the Jesuit plaza in front of the church was finished.
