This oak altarpiece bears the mark of one of the finest workshops in Antwerp and forms a rectangular structure in which the figures, isolated or connected to the architectural elements, all fit with the others in the scene. They portray the shepherds' adoration of the Infant Christ in an urban setting.This nativity scene is the finest example of this genre in Portugal and is unique not only because it represents just one scene but also for the quality and preservation of the polychrome and the gilt work. It formerly belonged to the Monastery of Santa Clara.
