Church of Tenaún, Catholic church in Tenaún, Dalcahue, Chile

The Church of Tenaún, also called Church of Our Lady of Patrocinio, is a Catholic church in Tenaún, Dalcahue, on Chiloé. It measures 42.40 m long and 14 m wide, with a central nave 6.90 m high, side naves 4.30 m high and a tallest tower of 26.10 m. It rests on a base of stone and coigüe wood; the structure is mainly tepa, tenío and canelo, the interior lined with larch, the exterior clad in larch tiles and Guaitecas cypress, and the roof is corrugated galvanized iron.

The Church of Tenaún was declared a National Monument of Chile in 1999, and on 30 November 2000 it was among the 16 Churches of Chiloé inscribed as UNESCO World Heritage Sites. Restoration work followed: the building was restored in 1999, the tower and facade between 2005 and 2006, and the nave and vault between May 2010 and May 2011.

The name Tenaún means "three peaks" in the local indigenous language, and the church's three pillars are believed to symbolize them. The patron saint is Our Lady of Patrocinio, whose feast is celebrated on 30 January. The church heads the Patrocinio San José parish, one of 24 in the Diocese of Ancud.

The church stands in Tenaún, in the commune of Dalcahue on the Chiloé Archipelago, and is reached by road from Dalcahue; the surrounding settlement is small, so services and opening depend on parish activity. The patronal feast of Our Lady of Patrocinio falls on 30 January. The building was restored in 1999, the tower and facade in 2005–2006, and the nave and vault between May 2010 and May 2011.

The three pillars inside the church are believed to echo the name Tenaún, which means "three peaks" in the local indigenous language. The building was declared a National Monument of Chile in 1999, a year before UNESCO listed it with the other Churches of Chiloé on 30 November 2000.
