The structural frame was originally intended for a church in Ancon, Peru, but was diverted to Arica after the 1868 earthquake.
The interior is notable for its cast-iron columns, which mimic stone vaulting and Gothic arches.
The original stained glass windows were imported directly from France to fit the prefabricated panels.
The church was assembled using a sophisticated system of bolts and iron plates, eliminating the need for traditional mortar or heavy masonry.
It remains one of the few surviving examples of colonial-era industrial architecture from the Eiffel workshop in South America.
The structure is designed to be lightweight, a specific engineering choice to minimize structural failure during tectonic shifts.
St. Mark's Cathedral is a metal-framed Gothic Revival church designed by Gustave Eiffel's workshop. Located in the heart of Arica, Chile, the structure was prefabricated in France and assembled on-site in 1876. It was commissioned by Peruvian President José Balta to replace an older church destroyed by a major earthquake in 1868. The building is constructed primarily of galvanized iron plates and features a distinctive Neo-Gothic aesthetic rarely seen in this region. It was declared a National Monument of Chile in 1979. The cathedral served as the focal point for religious life during the transition of Arica from Peruvian to Chilean territory. Its modular construction allows the walls to withstand the seismic activity frequent in northern Chile.
From the Plaza Colón across the street for a full perspective of the Gothic facade.
Visit during the late afternoon to see the sunlight filtering through the colorful stained glass windows.
Walk around the exterior perimeter to observe the visible iron-plate construction seams.
Combine this visit with a trip to the nearby former Customs House, also an Eiffel design.
Do not attempt to touch the metal walls or structural rivets.
Maintain silence; modest clothing covering shoulders and knees is expected.
