Alhué church is erected in a single nave, with a lintelled ceiling decorated with moldings. It has wooden floor. Two large double-wing doors, also of wood, welcome worshippers. The nave is underpinned by the Main Altar with the town’s patron, Saint Jerome, accompanied by two images: one portraying the Immaculate Conception and the other one, the Sacred Heart of Jesus. Frontly, there are two lateral altars that along with the Main Altar give rise to the presbytery; the three wooden altars date from the colonial period. In the right lateral altar (from the entrance towards the Main Altar), Saint Francis of Assisi is venerated. In the left lateral altar there is a replica of the Cross of Chile.

Lateral walls display “bull’s eyes”, lateral doors, confessionals and a minor altar with an image of the Virgin of Carmel, located in the gap of one of the lateral doors.

Most images are made in plaster or fiberglass. A Christ figure made of polychrome wood and human hair draws everyone’s attention. Hair would have been changed in 1882, because the original was moth-eaten. This image, as we are told, would be since the beginning, and it is located close to the choir. It is worth mentioning the baptismal bath dating from 1623: it is a beautiful cast iron work with an image of Saint John the Baptist.

Alhué Museum exhibits a myriad of objects that were a part of the chapel and the Parish House.
