 Both transept arms and the main chapel of the apse are decorated with huge, magnificent gilt wood altarpieces built between the 17th and 18th centuries which are fine examples of the so-called "national" Portuguese altarpiece style.The lateral chapels of the nave have altarpieces in Mannerist and Baroque styles.The 17th-century choir stalls of the main chapel were brought from the Old Cathedral, as was the intricate stone baptismal font, carved by Pero and Felipe Henriques in late Gothic-Manueline style in the beginning of the 16th century.
