Church of Our Lady of Grace of Nercón, or Iglesia de Señora de Gracia de Nercón, Chiloe Island, Chile was made a National Monument of Chile in 1984. It is considered as one of the best examples of Chiloe Chilota architecture. The wooden churches of the Chiloé Archipelago in the Los Lagos Region, Region X, Chiloe Province, Chile are examples of the Chilota style of architecture. Unlike classical Spanish colonial stone architecture, the churches of Chiloé are made entirely in native timber with extensive use of wood shingles. The churches were built from native materials to resist Chiloé Archipelago's humid and rainy oceanic climate. Built in the 18th and 19th centuries when the Chiloé Archipelago was still a possession of Spain, the churches are a mix of European Jesuit culture and local native skills and traditions. They are an excellent example of mestizo culture. Sixteen of the churches of Chiloé were designated UNESCO World Heritage Sites in 2000.
