The church of Sant Fèlix will be a delight to the visitor's artistic sensitivity. Its architectural configuration, with its basilical ground plan, reveals its Romanesque origin; this is a structure with three naves (the central nave has a barrel vault and the side naves form quarter spheres) with the four arcades which separate the naves and the corresponding circular pillars supporting it.

But Sant Fèlix's finest Romanesque-epoch architectural and sculptural reference is its facade; this is formed by four semicircular decreasing arches, protected by a decorative dust-guard with the typical chequering (which originated in Aragon and Navarre). The tympanum boasts a curious sculptural unit with the representation of the figure of Christ, crowned and enthroned, surrounded by the Tetramorph. Another outstanding element is the tombstone (of funeral origin) embedded at the top of the facade.
The Gothic inheritance is patent in the construction of the belfry, which dates from the 14th and 15th centuries; it is attached to the west wall of the church and its base might suggest a certain defensive origin.
