Casteldoria Castle was built around the 12th century by the Genoese Doria family, and passed from the Genoese dominion to the Aragonese, then to the Arborea Giudicato and lastly to the Malaspina family.
Only a few ruins remain of the fortress: parts of the walls, the remains of a chapel and a large cistern that was probably used to collect and store water. The famous tower, on the other hand, is well-preserved, and is an important part of the castle, built in large, rectangular granite blocks set in mortar. Twenty metres high, it has a pentagonal layout with the entrance on the north-eastern side. On the same side are two large, non-aligned openings, and a large window on the opposite side on the first floor. Inside, the castle has three wooden floors with a tiled roof and walkway. The last floor was created from what was originally a mezzanine floor before a terrace.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.
