Built at the end of the 13th century, probably on the site of the old mosque, this Gothic style has a floor plan in the shape of a Latin cross, with three naves, a triple apse and also a main doorway with a pointed arch in a style similar to that of the Monastery of Batalha.
One of the main sources of interest in Silves Cathedral is the chancel which was built at the end of the 15th century in the Manueline style, the principal features being the ribbed vault and the tomb of D. João II.
After the 1755 earthquake, some repairs were needed, as can be seen from the late Baroque style of what is known as the “Porta do Sol” (Door of the Sun), dating from 1781.
Amongst the artistic treasures of this church, the Baroque altarpiece in the chapel Capela do Santíssimo (Most Holy) and a jasper statue of Our Lady, dating from the late 15th or early 16th century, deserve special mention.
