Encinas Castle is dated back to the 14th century. The castle consists of a small and square enclosure, with two square towers in two of its corners. One of these served as the keep. In the other two corners the crenelated walls are raised to the same height as the two towers thus giving the false impression that the castle had four towers. There is a small stone ditch at the feet of the walls, which is provided with a low defensive wall.
In the 1950's the ruined castle was acquired by the Ministry of Agriculture. They restored it and turned it into a cereal silo. During these restorations however they blinded original windows and totally destroyed its medieval interior.References:
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.
