The altarpiece representing the Tree of Jesse is adapted from an earlier work, possibly existing until the end of the 17th century and is not part of the original church. The tree, carved out of multi-colored wooden leaves, in which the 12 figures of the kings of Judah appear, standing, supported by the branches of a tree trunk that rises from the lying body of Jesse, at the top, there is a sculpture of the Virgin with the Child, preceded by the evangelical figure of St. Joseph. In the niches that surround the altarpiece, the statues of Santa Ana and São Joaquim can be seen together with those of four Franciscan doctors who wrote about o Immaculate. The work is known to be by artists Filipe da Silva and António Gomes for the existence of a contract dated 1718.
