The Nuestra Señora de los Dolores de Loica Bajo church, located close to the Loica estuary and declared Historical Monument on September 10, 2010, was founded by Archbishop Rafael Valentín Valdivieso on March 14, 1856. The building was completely destroyed by the 1909 earthquake. Thanks to the donation of some lands, a new temple was erected, recovering the old church shape, but located a bit farther. The church, as is known nowadays, was blessed on March 26, 1926 by priest Bibiano Bustos.

With elements from neo-classical architecture, a building composed of two volumes, a nave and a tower, where the steeple with a hipped roof stands out, was erected. Parish House is perpendicularly attached to the building. It was destroyed after an earthquake, but it was rebuilt maintaining its volume and expression. In front of the Parish House there is a front yard forming a large atrium and meeting area.

Adobe walls are painted in white inside and out. Wood structure is of alamo; roof beams are of oak, and the roof is of zinc. It has four windows distributed along lateral walls, two windows on the main wall and three double-wing doors.

After the 1985 earthquake, the main wall was seriously damaged, apart from other damages on lateral walls and tower. Therefore, it underwent some modifications born of the repairs made. There are records of these modifications, and they could be taken into account for future restorations and keep its authenticity.

The 27F earthquake damaged it too. Due to the damages, the National Council for the Arts and Culture approved a fund for carrying out a research project aiming at its reconstruction.

However, the community has managed to –by dint of hard– obtain some donations with which minor repairs have been made in order to keep this patrimonial building going.

Loica, Alhué and Petorca churches have similar architectural characteristics and are visible landmarks in Central Chile for Jesuit missionaries instructing in the Christian faith.
