Church of Aldachildo, Roman Catholic church in Puqueldón, Chile.

The Church of Aldachildo is a wooden building located on Lemuy Island in the Chiloé Archipelago, displaying the regional architectural style of religious structures in southern Chile. The building has a simple, functional design typical of churches found throughout this area.

The Church of Aldachildo was completed in 1910, according to the Spanish Wikipedia article, though the English article places its completion at the end of the 19th century. It was declared a National Monument of Chile in 1999 and, on 30 November 2000, became one of the 16 Churches of Chiloé inscribed as UNESCO World Heritage Sites. Its materials have not been replaced.

The church serves as the center for celebrations honoring Jesus of Nazareth on August 30th and the third Sunday of January, bringing together the local community. These occasions show how deeply the place is woven into daily religious life on the island.

The building shows wear on its exterior panels and interior surfaces, but remains open to visitors. It is wise to step carefully when entering and be mindful of the condition of the wooden structure.

The church keeps its original materials: no repairs or replacement of parts are recorded, though the exterior and nave panels show some wear. It was declared a National Monument of Chile in 1999, a year before the UNESCO listing of 30 November 2000.
