Gradually introduce the European architecture, but appropriate to the medium Chiloe, ie built on the island abundant materials such as wood.
From the basic scheme, the missionary churches chilotas must undergo an evolutionary process that will engage a long time to come to define its type, first as a work of the Jesuits is developing the spacecraft, then during the Franciscan regime, second half of the nineteenth century definitely ends to form the tower facade with its three elements. Throughout this process the influence of carpenters chilotes is essential and end up giving to churches chilota unique architectural value in the world.

The chapel appears as the element that gives birth and meaning to the villages, and around it, the set is his first order: the church located in a way that is seen everywhere. Facing the plaza is located the churches: a place of ceremonies and meeting neighbors.
The church is transformed into the center of each sector recognizable island, instead of calling regular and sacred area. And then attached to these churches, rose a lower house called casemita (mita house) as a room for priests. Over time, it also incorporated the cemeteries near the buildings of the churches, thus preventing the burial of the dead were made to the Indian fashion.

Thus we can say that the constitution of the church chilota, such basic geometric building next to the plaza since it was not a situation or self-imposed a moment, but is a slow process that began in early or during the sixteenth century , from the concourse area as a religious site of encounter and action.
For the construction and maintenance of missionary chapels system was used to working in solidarity with the Indians, called Minga, where neighbors contributed materials and labor.
Today you can find dozens of these scattered churches in Chiloé, with a very old data continue to be used as in earlier times. The churches are being damaged naturally over time and have been the communities that maintain them. So you can find churches in 300 years but in reality the building already exceeds the third or fourth generation due to arrangements and reconstructions made by neighbors.
Within the churches belonging to the old school of Architecture chilota Wood is currently posted on 60 buildings that are still in time, as living testimony of a centuries-old tradition.
