Orihuela Cathedral it was built above a pre-existing Muslim mosque as a simple parish church and was later converted into main church by order of King Alfonso X of Castile in 1281. In 1413, pope Benedict XIII elevated it to the rank of collegiate, until it became a cathedral in 1510.
Construction was begun in the late 13th century in Valencian Gothic style, with a Latin cross plan including a nave and two aisles, an ambulatory and chapels within buttresses. The crossing, the late-Gothic great chapel, and the ambulatory are 15th century-early 16th century additions, including the removal of two pillars of the nave to obtain a taller vault at the crossing, after a design by Pere Compte.
The interior receives little light due to the small size of the windows. There are three entrances: the Puerta de las Cadenas (Portal of the Chains, 14th century) is in Islamic style, the Puerta de Loreto (mid-15th century) is Gothic, and Gate of the Annunciation (at the north, built in 1588 by Juan Inglés), in Renaissance-style triumphal arch-shape. Other Renaissance elements include the stalls and the grills of the choir, and the cloister (originally from 1377, but rebuilt until 1560). The oldest part is the bell tower, which dates from late 12th-mid 14th centuries. It has four floors covered by groin vaults.
Annexed to the church is a museum of Sacred Art, housing works by Diego Velázquez (Temptation of St. Thomas), Vicente López Portaña, José de Ribera, Juan de Juanes, Francisco Salzillo and other artists.
The large organ is from the Baroque renovation, and was realized in 1733 by Valencian craftsmen.

Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
