The Church of Saint Philomena was designed by the French architect Eugène Joannon in 1892 and its construction was concluded in 1894.

Joannon’s work stands out given the mixture of styles, predominantly the neo-Gothic style of the church. The church is formed by a cross-type floor layout, with three parallel naves, the central nave being the highest.

The naves are separated by ogival pointed arches, which are sustained by polistil or clustered pillars that extend through the nerves of the groined or ribbed vault. The complements or lengths are concave, adapting to the curvature of the vault.

The capital of the pillars is adorned with floral motifs. The clerestory has 6 trefoil arches with simple pillars in the same style as the main ones and complies with an ornamental rather than a gallery one.

The clerestory has large windows with ogival pointed arches that provide great luminescence to the area.

On the walls, where the transept finishes off, there is an ogival arch that has large ceiling roses on both parts. However, most of the luminescence of the transept is due to the large windows of the lateral walls clerestory.

The retro choir starts as an extension of the lateral naves and is formed by an arcade in the same style as that of the central nave, continuing the polygonal form of the apse. Similarly, it is covered with ribbed vault and smaller windows, two large ogival arch vertical windows and one in the circular center. The lateral naves can be appreciated in the same way. The zone of the presbytery is also illuminated by large ogival arch windows.

The choir is over the entrance and it is semicircular in shape and has a wood balustrade that forms the ogival pointed arches. Additionally, there are two large windows similar to those in the clerestory of the central nave.

The entrance is gabled con ogival pointed archivolts and there is a brown aluminum inner door, with glass windows. The entrance door is made of wood. Over the archivolts and linked to the choir you can appreciate the ribs shaped like a fan, in the manner of the palm vaulting characteristic of Gothic architecture.

In the exterior we can observe the flared portal with ogival pointed arches and a triangular pediment. An octagonal base tower can be observed, formed by ogival pointed arches and wood points. Further below, there is a niche formed by ogival pointed arches. Buttresses can be seen on the side.

Finally, the building is made of brick and the interior of the building and façade have been covered with stucco. The ribbed vault is made of wood.
