The joint tomb of King John I of Portugal (d.1433) and his wife Philippa of Lancaster (d.1415) stands under the star vault of the octagon. Their statues lie in full regalia, with clasped hands (expressing the good relations between Portugal and England) and heads resting on a pillow, under elaborately ornamented baldachins. The coats of arms of the houses of Aviz and Lancaster are on top of these baldachins, together with the insignia of the Order of the Garter. On the cover plate of the tomb are inscribed in repetition the mottos of the king "Por bem" ("for the better") and of the queen "Yl me plet" ("I am pleased").
