The stone-capital has disappeared. The stone-support has a rectangular section, is leaned against another flagstone placed in the rear and two smaller stones, both well worked ones, help it to be sustained, one by each side (it is fit between those). The precinct, quite well preserved, is of semicircular plan and straight or very lightly concave facade, with a door of monolithic stanchions and step. The interior adornment, this of the main precinct as well as this of the corridor that is originated by the potent walls of the facade, shows several "chapels" or "niches"; we also find the habitual monolithic pillars, with capital, leaned against or embedded in the wall, and the isolated pillar on the right of the central pilaster.
