The Church of Santa María de Loreto de Achao (Spanish; Castilian: Iglesia de Santa María de Loreto de Achao) is a Roman Catholic church located in Quinchao Island's largest town, Achao. Often referred to as the Church of Achao (Spanish; Castilian: Iglesia de Achao), is within the Diocese of Ancud, and was built around 1740 when Chiloé Archipelago was still a part of the Spanish Crown possessions.[1]
The Achao church is one of the oldest traditional Chiloé churches built in the 18th and 19th centuries, and survives almost intact from de Jesuit mission era.[2] It belongs to a group of 16 iconic wooden churches that were declared as a UNESCO World Heritage Site under the Churches of Chiloé's denomination[3] because of their unique form of wooden architecture known as the Chilota School of Religious Architecture on Wood.[4]
