The refectory was built in 1517/18 by Leonardo Vaz and his team of master builders. With its multi-ribbed, low vaulted ceiling the refectory exemplifies the principle style of the Manueline period.
Below the thick stone ropes, the walls are covered with azulejo tile panels dating from 1780-1785. The panels depict the Miracle of the Bread and Fish in the New Testament (north end) and scenes from the life of Joseph in Egypt from the Old Testament (side walls).
On the wall facing the windows there was a small wooden pulpit for the reading of the Holy Scripture and from the Lives of the Saints during meals.
On the north side is a 17th century painting representing St. Jerome, which is attributed to the court painter Avelar Rebelo. At the southern end, over the heating chimney, one can see an oil mural, "Adoration of the Shepherds", attributed to António Campelo (late 16th century), which was restored in 1992.
