Iglesia de San Francisco

Academic in architecture of the FAU, Natalia Jorquera, undertook in 2013 an investigation that represents an in-depth exploration of the origins, evolution and structure of the church of San Francisco (Santiago de Chile) through the study of materials, design, shape and construction. Together with an interdisciplinary team from different countries, the researcher determined the age of the materials used in the construction and the density of the walls, using high technology mechanisms. During the work it was possible to determine the different phases of construction of the church, which began with a structure of the Andean churches of the colony, and then had reconstructions of different parts in the wake of the earthquakes, also with additions and extensions. One of the most surprising findings was the alleged anti-seismic system found in the foundations of the structure. According to the scholar, by the date on which the construction of the church began (1586), it is presumed that "it was Pre-Hispanic knowledge that collaborated in making the church seismic resistant."
