In 2012, I visited four of the sixteen UNESCO registered churches: San Francisco de Castro, Nuestra Señora de los Dolores de Dalcahue, Santa María de Loreto de Achao, and Señora de Gracia de Nercón. 

When I visited, the Church of Senora de Garcia de Nercon had yet to be restored.  When I compare the photos that I had taken in 2012 of the Church of Senora de Garcia de Nercon to the more recent photos I found online, I can see that the entirety of the church's steeple and outer walls of the main floor are reconstructions.

The churches of Chiloé, by themselves, may lack the brilliance and the scale of the world's grand churches, but these churches are to be best appreciated in their setting, that is to say, the quiet and moody atmosphere of the Chiloé archipelago.
