It is a small and simple Chapel, shows of the late Romanesque of the 12th century and built on the remains of another oldest, linked to the fortress built in the 10th century for defending the lands of Santiago of the Norman invaders.
The main façade is very simple and its unique embellishments are a small bow pointed to over the door and a unique rosette
The rear facade is the apse, semicircular shape and four attached columns.
The side facades are also very simple, highlighting the eave Corbels. In one of them there is a second entry with a semicircular arch.
The chapel has a rectangular plan, with a nave in two stages separated by an arch on columns. A slightly pointed vault is the cover of the main nave.
Stands out especially in the interior of the Chapel, Baroque altarpiece.
Nowadays it is very well-preserved and closely related to the rite of the bathroom of the nine waves.
