Iglesia de San Isidro Labrador, Roman Catholic church in Santiago, Chile

The Iglesia de San Isidro Labrador is a Roman Catholic church in Santiago with a rectangular plan defined by two tall columns at the front. Neoclassical triangular pediments frame three doorways, and a central circular window filters light into the interior space.

Founded on 15 May 1686 by Bishop Diego de Umanzoro, the parish first stood in adobe among fields and corrals. In 1754 the Marquis of Casa Real, Francisco García Huidobro, had it demolished and replaced with a lime-and-brick church on stone foundations. A third church was built 100 m south between 1842 and 1848 under priest Blas de los Reyes, and the fourth, by architect Ignacio Cremonesi, was completed in 1903. After the 1906 earthquake Ricardo Echeverría added a dome over the main altar, which collapsed on 2 December 1921.

The parish is named after Saint Isidore the Labourer, a Madrid farm worker born around 1081, canonised in 1622. He is said to have scattered handfuls of seed outside the fields so that birds could find food. The church keeps its pastoral and evangelising work in the sector, and its feast day falls on 15 May.

The church sits at the corner of San Isidro and Santa Victoria streets in the Santiago commune. Regular services take place, so it is worth checking when visiting to find accessible times to look inside.

The interior ceiling features five small domes with lowered curves designed using Roman structural principles to reduce weight on the walls. This engineering approach from ancient times was retained when the building was reconstructed in the early 1900s.
