Together with the Aiamans palace and the Plaza de España, it forms part of a beautiful architectural ensemble in the center of the town. The parish church, in neoclassical style, consists of a single nave covered with a half-barrel vault, with lunettes and supported by stone pilasters, on which are supported semicircular arches, and walls topped with an airy and bright cornice. It has four chapels on each side. In the altarpiece of the main altar is venerated the image of Our Lady of Lloseta, a carving of the Roman-Byzantine iconography, from the late twelfth century and early thirteenth century. Added to the temple, to the right of the main altar, is located the chapel and crypt of the Counts of Aiamans, where the mortal remains of the family are kept.

The Oratori del Cocó was built in 1878 and is the place of pilgrimage for all the "Llosetins i Llosetines" as it keeps the "Mare de Deu de Lloseta" for which the locals feel a great devotion. The Oratory itself was built on the grounds of the Possesió de Son Ramón, this Possesió belonged to the lands of Ayamans but when the latter was divided in the sixteenth century.
