After receiving numerous donations and possessing extensive territories, it entered decadence in the fifteenth century. In 1592 and 1615 it was grass of the flames, reason for which it had to be rebuilt. The permanence of the monks remained until 1835, date in which the exclaustrado with the confiscation of Mendizábal took place.

The west, which is now the entrance, is a pointed arch, standing out its beauty by the simplicity of its construction and decorative elements based on floral elements, figures of monks and the calvary of the tympanum of the door. In the south gable rises the belfry that is of later times.
In its interior they emphasize the sarcophagi of the founders, arranged to both sides of the altar, in the middle mounted the major altarpiece in which participated between 1605 and 1618 Pedro Sánchez, Cistercian monkReferences:
The Palace of the Kings of Navarre of Olite was one of the seats of the Court of the Kingdom of Navarre, since the reign of Charles III 'the Noble' until its conquest by Castile (1512). The fortification is both castle and palace, although it was built more like a courtier building to fulfill a military function.
On an ancient Roman fortification was built during the reign of Sancho VII of Navarre (13th century) and extended by his successors Theobald I and Theobald II, which the latter was is installed in the palace in 1269 and there he signed the consent letter for the wedding of Blanche of Artois with his brother Henry I of Navarre, who in turn, Henry I since 1271 used the palace as a temporary residence. This ancient area is known as the Old Palace.
Then the palace was housing the Navarrese court from the 14th until 16th centuries, Since the annexation (integration) of the kingdom of Navarre for the Crown of Castile in 1512 began the decline of the castle and therefore its practically neglect and deterioration. At that time it was an official residence for the Viceroys of Navarre.
In 1813 Navarrese guerrilla fighter Espoz y Mina during the Napoleonic French Invasion burned the palace with the aim to French could not make forts in it, which almost brought in ruin. It is since 1937 when architects José and Javier Yarnoz Larrosa began the rehabilitation (except the non-damaged church) for the castle palace, giving it back its original appearance and see today. The restoration work was completed in 1967 and was paid by the Foral Government of Navarre.
