The church of the ancient Monastery of Saint Felix, of the Canonesses Regular of Saint Augustine, signals a Christianised place since old times, as it is evidenced by the archaeological remains that can be seen in the City Museum. The origin of the religious home dates back to the 10th Century, with the relics of Saint Felix, Saint Adrian and Saint Natalia being worshipped in this church, which was renovated several times. Special attention should be given to the Manueline portico and porch covered with polychrome tiles from the 17th Century. Due to a fire, the interior of the church is deprived from the former Baroque covering. The ancient monastic spaces still have a variety of chequered tiles, patterned tiles, Albarrada tiles and individual figurative tiles.
