The first Alhué church was built around 1753 when the Villa San Jerónimo de la Sierra de Alhué was founded. This early building made out of adobe, wood and thatched roof was temporary, and in 1764 a new 12-rod construction with adobe walls and thatched roof. Later, in 776, it was replaced by a wider building (24 rods long and 9 rods wide), and continued growing until it had its current magnitude and size. No one knows who the author of these works is.

It was built on quarried stone foundations with adobe walls, wooden roof and clay tiles; it has experienced some modifications over time. In 1835 the adobe tower was demolished; in 1879, the whole roof was replaced; in 1900 the current wooden tower was built. In 1870, the Parish House and the central nave of the church were built.

The 1985 earthquake seriously damaged the church: walls fell and the structure ended up inclined, but 10 years later a revamp project would end with a second zero-restoration in 1999. In 2010, another earthquake seriously damaged its structure. In 2014, a restoration project under the direction of the School of Architecture and Urban Planning at the UNIACC University has returned it to a functional status, although there are still many pending tasks.

The church, with a classical Colonial architecture, stands out for having a nave with adobe painted masonry. However, due to the fact that confessionals were embedded into the walls and such works are not authorized by the Council for National Monuments, completion works would be halted; that is why a side of the nave is painted and another has the adobe exposed. Exposed adobe in the background walls of altar reredos can also be observed. Lintelled ceiling is decorated with some moldings.

The church receives some natural light through “bull’s eyes” located and distributed along lateral walls of the nave. A skylight timidly illuminates presbytery. On the outside, lateral walls reveal abutments.
