Iglesia de San Miguel Arcángel, Calbuco, Catholic church in Calbuco, Chile

The Iglesia de San Miguel Arcángel is a church built entirely of wood in Calbuco, in a Central European neoclassical style. It measures 33 metres long and 19 metres wide, and its tower rises 30 metres. The present building was erected in 1935 after the 1930 demolition of its predecessor.

The first parish church was established in 1620 by Bishop Luis Jerónimo de Oré near an existing colonial fort that had stood since 1602. The building evolved as the primary church of the region and underwent structural modifications over time.

The town's patron saint is Saint Michael, whose image is said to have been brought by Spanish founders in 1603. Since 1712 the Fiesta de los Indios Caciques has been held here at Ascension, recalling the local chiefs' return of the stolen image after the 1712 Huilliche rebellion. The Fiesta de las Luminarias takes place every 28 September, and the Cofradía de Fiscales San Juan Bautista still officiates in the absence of priests.

The church stands in Calbuco, in the Los Lagos Region of southern Chile, and is built entirely of wood, so visits are best planned around the parish's religious calendar. Two festivals draw crowds: the Fiesta de los Indios Caciques, held at the Ascension, and the Fiesta de las Luminarias on the night of 28 September.

Parish records housed within the church date back to 1710 and rank among the oldest religious documents of southern Chile. These historic registers offer glimpses into early colonial life and the region's development.
