 Although the facades are plastered and whitewashed, the foundations, doorways and windows are projected cornices, with wedge pilasters on the corners, while the building is surmounted by pinnacles and crosses on most gables.The principal facade, with vibrant entablature and metopes, is overlaid by a triangular pediment, with the tympanum hosting an image of "Nossa Senhora da Misericórdia" ("OurLady of Mercy").An arched portal-arched, based on Tuscan capitals, is framed by a space defined by Tuscan pilasters, supporting a curved pediment over a metope entablature.
