Built during the reign of Philip I, its austere walls are decorated only, over the main door, by the coat of Misericórdia arms (compassion, mercy and charity), carved in white marble, with the five wounds of Christ on a sophisticated palette surmounted by a crown of styled thorns. Inside is dominated by the carved altarpiece, from the mid-18th century, exuberant in its sculptural detail and use of colour, in imitation of rich-coloured gemstones among gilt elements.
