Structural configuration: small building, isolated and with a Greek cross plan surmounted by an octagonal lantern. The three chapels and the building that constitutes the entrance are covered with barrel vaults. Between the left chapel and the central one is the access to the sacristy, a pentagonal room with an umbrella vault. The vault of the central body is a lowered basin set on an octagonal lantern with windows. The internal walls and vaults are richly decorated with wall paintings and stuccos. The external facades are plastered and painted, with the exception of the basement which is unfinished and reveals a very irregular stone masonry. The building is equipped with a small bronze bell, positioned in the front part, on the lantern, supported by a structure and protected by a roof, both made of metal.
