 Chiloé, in part because of its physical isolation from the rest of Chile and access to different materials, has a unique colonial architecture that differs substantially from typical Chilean Spanish colonial architecture.The Spanish, who arrived in the 16th century and their Jesuit missionaries who followed, constructed hundreds of small wooden churches as part of the Indian Reductions mandated by the Crown for Spanish colonization of the Americas.The result was a mixing of Catholicism and indigenous Chilean beliefs.
