The original retable behind the altar is of stone, consisting of three arches in which the Lord's Prayer and Decalogue are inscribed.
Francisco de Comontes, a son of Iñigo de Comontes, executed in 1533 the principal retablo of the chapel of Los Reyes Nuevos in Toledo cathedral, from the design of Felipe de Vigarny.
In 1522 he got a commission for a retable in Ançã limestone (a local limestone) for the Monastery of São Marcos de Tentúgal (near Coimbra).
It is noted that the retable, the communion rail and pulpit won a prize at the first Vatican Council held in Rome in 1870.
