Established in the 13th century, the church was expanded in several phases, culminating in the current 15th-century Gothic structure. During the late 17th century extensive Baroque renovations were carried out to the interior, the most significant of them being ceiling frescoes. This remarkable set of frescoes completely covers the vault of the nave and the presbytery, and illustrates the lives of St. Nicolás and St. Peter. They were designed by the Italian master Antonio Palomino and painted by his student, Dionis Vidal, and have been completely restored.Tourists are not permitted to visit during mass or other liturgical celebrations.
